Lindsay Lohan is apparently putting last week's scuffle outside of a New York City nightclub, and her subsequent arrest, behind her.

The Liz & Dick starlet hit up Q102's Jingle Ball concert in Philadelphia, and we're told she hung out backstage with boy band The Wanted. She even signed some autographs for her adoring fans.

You may recall, The Wanted's singer Max George was reportedly involved in the nightclub brawl in which Lilo is said to have punched a woman in the face ... but George has denied any involvement in the fight.

Lindsay is a wanted woman!
