Miley Cyrus Twerks on Santa, Ariana Grande Spreads Cheer at Jingle Ball

From Miley to Macklemore, pop’s biggest stars rung in the holidays at 102.7 KIIS FM’s Jingle Ball in Los Angeles on Friday.

Following their seven Grammy nominations, Macklemore & Ryan Lewis rocked the Staples Center and brought out Schoolboy Q to perform “White Walls.”

Despite feeling under the weather, pint-sized diva Ariana Grande was cute as can be in a wintery white dress while singing an acoustic version of “Honeymoon Avenue” and her holiday single “Last Christmas.” She had technical difficulties during her set, but that didn’t stop her.

“I’m sorry if my mic was off the whole entire time. At least you know I’m not a track, right?” she told the crowd.

Some interpreted the comment as shade, but she took to Twitter to clear the air. “Ohhh jesus. I wasn’t throwing shade AT ALL I didn’t even see anyone else’s set. I was sick backstage that’s why I didn’t even do the carpet,” said Ariana.

Miley Cyrus was more naughty than nice during her provocative performance. The pop singer remixed her set for the holidays, twerking on St. Nick and dancing with sexy reindeer and a Christmas tree while performing “We Can’t Stop” and “#GETITRIGHT.”

“You are a VERY BAD Santa @CheyneThomas,” Miley told her friend.

Robin Thicke performed “Blurred Lines” with T.I. and caught up with his VMA partner-in-crime Miley backstage. His wife Paula Patton also stopped by to support her man, who was nominated for three Grammys earlier in the evening.

Jordin Sparks helped her boyfriend Jason Derulo cool off following his sweaty set, while other performers included Travie McCoy, Austin Mahone, Selena Gomez, and Enrique Iglesias.
