HAPPY BIRTHDAY!!! From Jeremy / JJ :3

p.s. youre unc level now

I’ve been a fan since Avatar The Way of Water, Spider was such a standout and you brought so much heart to the role. It’s been so fun watching your career grow and I’m genuinely sooo excited to see what’s next for you, Hope you have the best day ever, you deserve it! Love you 🩵🩵

I would also like to put it out there how your works are a relateable safe space for me. Thank you for bringing them life.

happy 21st birthday 😭🤍🤍🤍

i doubt you’ll ever see this but i’m putting it out there anyway because you’ve genuinely earned the words.

happy 21st birthday!! that number probably sounds crazy. like you’re officially in your twenties now, not just sneaking by in your late teens lol. i hope this year gives you the kind of happiness that sticks. the kind that doesn’t rely on big things, but shows up in little quiet ways too.

you’ve been my favorite actor since 2023, no exaggeration. and i don’t mean that in a casual “i saw a movie and liked your performance” kind of way. i mean like… your work has genuinely stayed with me. i can’t even count how many days i’ve put on avatar just to feel something again. or to feel less of whatever i was feeling actually. sadness, stress, anger — didn’t matter. something about watching you in that world just made things feel a little more okay. i don’t know if you realize the kind of comfort you give people, but it’s real. and it means a lot.

and it’s not just the characters. it’s you. something about your energy off-screen too feels rare. you come across grounded and self-aware but still goofy in the best way. humble, but you shine whether you’re trying to or not. that’s the kind of person people root for.

you’ve helped me more than you know. and i just wanted to say thank you. for existing, for doing what you love, and for unknowingly being a safe place for people like me.

so yeah. happy birthday again. i hope 21 brings you peace, success, and people who see you for you. if somehow this actually reaches you, just know you’re appreciated more than you probably realize.

🎈Happy Birthday, Jack 🎈

Today is your birthday… and I can’t just say "happy birthday" and leave it at that. Because you didn’t just come into the world — you lit up mine.

With your smile, you warm my soul. With your voice, you soften my heart. And with just one look, you quiet my entire world.

Having you in my life makes everything feel complete. Even when my mind is a mess, hugging you brings instant peace. Sometimes, just standing beside you in silence is the most comforting thing in the world.

I'm proud to watch you grow a year older. I want to share many more birthdays with you — sunrises, quiet moments, and all the little things that make life beautiful.

ps: call to the people in Google and tell them to write your birthday right, they made us clown for years 😪

I just wanted to say I’ve been a fan of yours since Avatar The Way of Water. Spider was such a cool character and you made him stand out. You brought so much heart to the role. It’s been so cool watching you grow and succeed in life—from Avatar to Scream, Freaky Tales, and more yet to come! I’m so glad and grateful that I get to watch you grow—not just in your career, but also as a person who does what’s right in this world and strives to be the best version of himself. Thank you so much, Jack. You’ve truly changed me, and I’ll forever be grateful for that!💙

Happiest of birthdays to you this 21st. What a special day for a special boy. I knew you were a special boy all along. The moment I saw you on my screen in 2022, I smiled, slowly… it crept on my face, the corners of my lips twitched upwards and my teeth slowly revealed through my parted lips. It was the biggest I’d ever smiled and I never smiled before that. You must be the most talented and uplifting guy to do this Jack… I believe in your talent and you are special. You have a special ability… I hope you harness this magic and spread it through the earth and world ❤️

Happy Birthday! You're turning 21, and I truly hope your day is as bright, warm, and full of joy as the light you bring into the world. I want to wish you not only a happy birthday but also a day filled with love, laughter, and the kind of moments that make you stop and think, “Wow, this is what life’s about.”

Congratulations on reaching this amazing milestone, 21 years of life, growth, and the kind of dedication that inspires people far beyond what you might realize. I want you to know how much your work means to me. Every project you take on, every role you bring to life, and every ounce of effort you pour into your craft carries a sincerity and passion that’s rare to find. It’s not just entertainment, it’s connection, comfort, and inspiration.

You have a way of making characters feel real, of telling stories that stay with people long after the credits roll. And for me personally, everything you do matters more than I can put into words. Your commitment, your energy, your kindness, it all resonates deeply, and I’m so grateful you share your talent with the world.

I hope this year brings you even more opportunities to grow, shine, and embrace everything that makes you uniquely you. You deserve all the success and happiness life can offer, and I’ll always be rooting for you.

Happy 21st, Jack. Here’s to many more years of brilliance, laughter, and dreams coming true.

I hope you’re having an amazing day I’m so happy for everything you’ve accomplished. You’re not only a great actor but also a wonderful person, and I can’t wait to see you go even further with your projects and dreams. I first discovered you as Spider in Avatar: The Way of Water, and right away I could see how much potential you had — and you’ve definitely proven it! You truly deserve the best, and I hope you get to read this 💗💗.

I love the way you make every character unique, your laugh that’s so contagious , and the passion you show when you talk about the things you love. Every time I watch you act, I feel a mix of admiration and joy, and I can’t help but smile thinking about everything you manage to convey with your talent.

You’ve become one of my biggest inspirations to pursue acting , and every time I watch your movies, it makes me want to work harder and chase my own dreams. I hope that one day our paths will cross and I’ll get the chance to meet you, even for just a moment, because it would be a memory I’d never forget.

Also, I hope you don’t eat all the cake by yourself today 😜—save me a slice!

Never forget that there are people all over the world who love, admire, and are inspired by you every day ❤️. Happy Birthday, Jack! I hope your day is as amazing as the happiness you give us.

Happy Birthday! 🥳✨

I don’t know if you’ll ever read this, but I wanted to take this special day to tell you something I’ve been meaning to say for a while: thank you for inspiring me so much.

Ever since I started following your work, I’ve seen how much love and dedication you put into everything you do, and that has motivated me more than you could imagine. I have this big dream of becoming an actress, and honestly, there are times when I feel scared and doubt myself… but seeing you reminds me that it’s worth fighting for what sets my heart on fire. 💗

I truly admire your talent, but I also admire you as a person — how genuine, real, and humble you are. Even though we don’t know each other, you’ve had a very special impact on my life. It might sound simple, but because of you, I’ve learned to believe in myself a little more and to never give up. 🫶🏻

I hope this birthday is everything you deserve and more. I hope you’re surrounded by love, happiness, and people who make you feel as special as you truly are. May this new year bring you exciting projects, beautiful memories, and endless smiles. Keep shining, Jack, because you inspire so many people… including me. ✨💗

With so much love,

Maru 💌💗💕

I want to take this moment to send you my best wishes and hope you spend your day with the people you love.

I’d like to tell you that you are truly admirable and your work is absolutely fantastic. Thank you for being who you are, your charisma shines so brightly and I hope no one ever dims that light.

It’s kind of nostalgic to see how fast you’re growing, HAHA 🥹 but also so inspiring.

You’re someone who has saved me even though we’ve never met.

Sincerely, a fan 💖

This year, I wish you good health and that you are surrounded by warm love. May you create many wonderful works, achieve success in everything you do, and may your life be filled with smiles and laughter. If there are days when you face obstacles or sadness, I hope you can overcome them​ and may you take them as lessons and motivation that make you even stronger.

I’m truly happy to be your fan. You are my inspiration, the reason I’m motivated to study English because I want to communicate like you. Now, I’ve become a better version of myself and I’m really proud of it. Someday, I will succeed just like you.

Ps.​ Whenever you feel like recharging your batteries, please come to Thailand. Our Land of Smiles is happy to welcome you. When you visit, you will find only fun, happiness, and smiles. When you return home, this will be another best memory for you.

With love,

from Thai fan 💗🇹🇭

It’s been a long time coming since I ever saw you on the big screen for the first time. Almost three whole years of knowing you and following you through a screen. We know sometimes we’re not what you’d want us to be, but somehow we’ve found a way to grow up and learn from and with you ✨

Today not only we celebrate one more year of you. But we cherish everything you’ve accomplished in the past ones. We see you and we love all the effort you put into something you love, we see you grow and come stronger every time. I wish you so much more of that love and happiness, people who appreciate you and experiences to enjoy. We can’t wait to see what life has for you and celebrate them with you. Here’s to 21! 🩵

For: jackcito💕

happy birthday jack! i’ve been following you since avatar: the way of water, and i was beyond excited when i saw you were cast in scream 6! such fun and incredible movies, i absolutely loved your acting!

ever since then, i’ve been watching every project you’ve been in and supporting you from afar. you’re an amazing actor and you have one of the brightest, most promising futures i’ve seen.

i’ve been basically growing up with you since we’re the same age, and what you’ve accomplished at such a young age is something you should be incredibly proud of, i know i am!

thank you por putting so much love into your work. i hope i can meet you someday and tell you all of this face to face. 💝

💌 love, sashy — @sashalovalle on instagram.

— jackcthinker, bells.

I remember the moment I met you, it was because you are a fancast for Wes Bennett in "Better Than the Movies", and it was one of the best things that happened to me because that year I was feeling terrible, trapped in fear of the future, and having a cool, funny actor who loves his job was all I needed at that time. I learned to be braver, remembered the importance of being kind, and was encouraged by the love you have for your work and how you always seem to want to learn more and more.

I know it's crazy for someone who doesn't know you to feel this way, but I don't care because I needed to learn all these things and it was worth it, so I hope your year is amazing and that you don't lose your light

I just wanted to say that you’re an amazing actor and a big inspiration to me. I really admire your talent, your smile, and how much passion you put into every role. Thank you for making me laugh, dream, and believe in myself. Keep shining — I’ll always be cheering for you! 💫

With love,
