Call him an icon. Call him a bad boy. Call him a total and complete breakdown waiting to happen.
But also call Justin Bieber a 20-year old... because he celebrates a birthday today!
The artist, of course, has come under the very harsh glare of the spotlight since turning 19, smoking a lot of weed; allegedly hurling eggs at his neighbor; driving very fast; and maybe sleeping with Brazilian prostitutes.
It's been quite the bumpy road for Bieber of late and it's incredible to think he's STILL too young to drink alcohol legally. Not that we think that will stop him any time soon.
Still, it's The Biebs' big day and he deserves a break. So help us honor the star below by clicking through 20 photo of Justin Bieber shirtless. You're welcome, ladies...
