May 2012 —
Bieber makes his bread and butter as a teen pop phenom, but his social circle spreads far beyond. His appearance as part of boxer Floyd Mayweather Jr.'s entourage at a fight in May 2012 had everyone do a double take. Lil Wayne and 50 Cent were also on hand.

June 2012 —
Bieber's immense fan base comes out in full force when the singer releases his album "Believe." The disc not only went to No. 1, but it also had the year's biggest entry on the Billboard 200. How many can do that and graduate from high school (which he did in 2012) at the same time?

October 2012 —

November 2012 —
Bieber's relationship with Selena Gomez seemed to end at the end of 2012, although their actions sparked rumors of reconciliation just about every other week. Regardless of their on-again, off-again status, Bieber chose to take his mom, Pattie Mallette, as his date to the 2012 American Music Awards.

December 2012 —
Bieber cleans up at the American Music Awards in November, but the young artist is left out completely when the Grammy nominations are announced a few weeks later. Add an alleged murder plot to the mix, and it's fair to say December 2012 wasn't the best month for the Biebs.

And into 2013 —
The start of the new year hasn't been any better -- a paparazzo dies in oncoming traffic after attempting to take a photo of the singer's car. A week later, photos hit the Web alleging marijuana use by Bieber. The singer kept his sense of humor through the ordeal, joking about it in his first stint as host of "Saturday Night Live." Here he performs in Washington in December.
