Happy 13th birthday! Welcome to the teens. It's going to be a bumpy, yet exciting ride you'll never forget or regret (well, maybe you'll regret a few things you're about to do).
Happy 13th birthday! There's no denying it! You're a teenager now, so you are ready for the most important thing in life: a smartphone.
Happy 13th birthday! It's time to face the music...and be a Belieber!
This celebration is a farewell party for your TWEENS, and a welcome party for your Teens. Happy 13th birthday sweetheart.
How you will live your life when you are 31 depends a lot on how you live your life when you are 13. So work hard, get good grades and be the best teenager the world has ever seen. Happy birthday.
