On Friday, Dec. 3, Lady Gaga, David Guetta, Gym Class Heroes, Taio Cruz, Flo Rida and Sean Paul performed at KIIS FM’s Jingle Ball concert in Los Angeles.

Gaga performed her newest hit ‘Marry the Night,’ and later donned a bedazzled red outfit for ‘Bad Romance’ and a black gown with a super plungin’ neckline that nearly hit her naval during other songs, including the holiday hit ‘White Christmas.’ Guetta also entertained with his superior DJ skills, while Travie McCoy led Gym Class Heroes through their onstage set. Taio Cruz and Flo Rida were also at the show, and Sean Paul made a comeback with his performance.

Earlier, on the red carpet, several stars showed up to the Nokia Theatre to take in the show and kick off the Christmas season. Willow was there, and the tween singer looked like snowball rather than a ‘Fireball’ in her wintery outfit, which included furry boots and black and white patterned leggings. Jessie Malakouti of Jessie and the Toy Boys also strutted her stuff for the paparazzi gathered at the event, and she looked great in her flowy mini-dress. Karmin looked old-school in their ’50s-inspired outfit choices, while Jenna Ushkowitz of ‘Glee‘ kept it casual and contemporary in jeans and black leather jacket.
