KIIS FM's Jingle Ball in LA was a star-studded extravaganza. On Friday, artists such as Lizzo, Billie Eilish, Normani, and Camila Cabello came out to celebrate the annual concert series with a few jolly performances. Lizzo sang her chart-topping hit "Truth Hurts" (clad in a fierce Santa coat) and Billie got the crowd going with her upbeat tune "Bad Guy." Former Fifth Harmony members Normani and Camila also left everyone in awe with their respective stagings and incredible dance moves. Halsey, BTS, Sam Smith, Katy Perry, and Louis Tomlinson even brought their festive spirits to The Forum and delivered exciting shows. Bummed about not being there?
