President Obama awarded Sir Paul McCartney, Nick Jonas rocked out on his guitar, Taylor Swift got hoarded by eager fans and Miley Cyrus, Ciara, Courtney Love, Kylie Minogue and Ke$ha looked pretty in black. Elsewhere, Justin Bieber carried a life-sized Stanley cup trophy and Gucci Mane, who was recently freed from prison, sported a diamond-encrusted ice cream cone pendant while performing at BET's "106 & Park." It all happened this week and we've got the pics to prove it.
