Sure, Z100's Jingle Ball 2010 brought some of the year's biggest celebrities -- like Katy Perry, Justin Bieber and Kim Kardashian, to name a few -- to a packed Madison Square Garden last Friday night. But when fans watch the Fuse broadcast, they'll see it was the show's onstage collaborations and special guests that made it an evening to remember.

First-time Jingle Ball performer and the night's first act Taio Cruz performed his hits, but it was his rendition of his new single, 'Higher,' with Travie McCoy that set the tone for the rest of the concert. McCoy would later return to perform 'Billionaire' with Bruno Mars, who started the duet with a short cover of Barrett Strong's 'Money (That's What I Want).' While B.o.B. didn't bring out Weezer frontman Rivers Cuomo during 'Magic,' he did invite Mars to join him for 'Nothin' on You' and Paramore singer Hayley Williams to sing 'Airplanes.'
