Fifth Harmony, Ariana Grande & Austin Mahone Rock KIIS FM Jingle Ball

jingleball-2013-120713Fifth Harmony, Ariana Grande & Austin Mahone all rocked the Staples Center on Friday as part of KIIS FM’s Jingle Ball in Los Angeles.

Fifth Harmony performed at the Jingle Ball village as well as on the mainstage. We love their personalized Letterman jackets!

Ariana was sick but still took the stage to belt out some of her hits. Despite a microphone malfunction, she worked the stage and gave a great performance.

Austin also took the stage and lots of celebrities stepped out to check out the show. Check out photos of 5H, Ariana, Austin as well as Madison Pettis, Kelli Berglund, Colton Haynes, and more.
