Lindsay Lohan was backstage at Wednesday's Q102's Jingle Ball at the Wells Fargo Center.

The "Liz and Dick" star is friends with English boy band The Wanted with whom she was recently partying in New York the night she was arrested for allegedly punching a woman she thought had taken her purse.

She was spotted Wednesday afternoon with the group at the Omni Hotel by Independence Park.

Other performers at Jingle Ball included Justin Bieber, One Republic, Ed Sheeran and PSY of "Gangnam Style" fame. See photos below.
