On Saturday night, some of music's biggest stars hit the stage at the Nokia Theatre in Los Angeles for KIIS FM's Jingle Ball concert. The show's surprise guest was set to be Maroon 5, but unfortunately, frontman Adam Levine was a bit under the weather.
"BREAKING NEWS! @maroon5 was the surprise guest but @adamlevine is sick #SaveAdam so instead we have @iamwill," the radio station tweeted.
But not all was lost. Especially not for fans of Will.i.am! In addition to the Black Eyed Peas rapper, audience members were treated to performances by Taylor Swift, One Republic, The Jonas Brothers and more. Plus, the stars weren't just up on stage—there were quite a few famous faces in the crowd!
E! News caught up with Dancing With the Stars: All Stars finalist Shawn Johnson who told us that the end of this season is, "a little bit of a relief, I mean, my body is very thankful that I'm done. But it's a family, so I'm gonna miss it, I'm gonna miss them and I wish I could do it again, but I'm done dancing for now."
Johnson also spills that she's developing her own show that she'll be hosting and is planning to open up a gym back home.
But that's not all! Watch the clip for more with Shawn, her Dancing partner Derek Hough and plenty of other celebs!
