Justin Bieber Parties Shirtless on His 21st Birthday – Photos & Video!

Our baby Justin Bieber is all grown up. We’ve been there when he grew allergic to shirts, and even stood by him as forgot how to button up his pants.

The shirtless singer turned 21 on March 1st, and of course, he celebrated in his customary controversial fashion, hanging out on a private island in Grenada with new girlfriend rumor, model Yovanna Ventura.

Justin took to Instagram to show off his birthday present, a 1965 Lincoln Continental. Nice car, but think twice before doing anymore drag racing: You’re 21 and that means they just might throw you in big boy prison next time you get busted for some dumb stunt.
