When in Rome ... Drake pointed out that the Boston Celtics' clover might not be so lucky after all during his performance at Power 106's Powerhouse 2010 concert in Anaheim, Calif this past weekend. Drake invited Kobe Bryant -- who came out on top after beating the Celtics 83-79 in Game 7 of the NBA finals -- to the stage before launching into his hit single 'Over' off 'Thank Me Later,' which, as we all know, is in stores and available online.

The Cali crowd was also blessed with another hometown treat when Snoop took the stage and performed 'Ain't No Fun' with Kurupt and Warren G. Diddy, along with his Dirty Money crew, surprised the crowd when they took the stage although not originally featured on the bill. Diddy was also joined by his youngest son Christian, who looked like a mini-Diddy, as they jumped into 'It's All About the Benjamins' and 'Mo' Money, Mo' Problems.' The music mogul admitted that his performance was impromptu and that he was just passing through as he apologized to the radio station for forgetting to sub in 'Power 106' for 'Hot 97.' Check out the footage from the show after the jump.
