The many styles of birthday boy Justin Bieber

The young heartthrob - The hairstyle that he will likely never live down—the one he was always flipping in a way that must have taken a toll on his neck—was a mainstay in Bieber's initial rise to fame. As for his outfits, they were simple combinations of jackets, tees, skinny jeans, and sneakers.
