The Wanted was just one of many performers at Q102's Jingle Ball concert in Philadelphia on Wednesday, but they had one very special guest supporting them backstage -- Lindsay Lohan!

Q102 tweeted an exclusive pic of the troubled star signing autographs backstage, where she watched the band perform. "EXCLUSIVE PHOTO: @lindsaylohan backstage at #Q102JingleBall where she's hanging with Max and @TheWantedMusic!" the station added, with the photo.

Of course, this isn't the first time LiLo has hung out with the British boyband. She also went to their performance at Justin Bieber's NYC concert last week, and hungout with band member Max George afterwards. Rumors of a romance between the two have been flying since Lindsay's bar brawl during their night out, which led to her arrest, after another woman allegedly caught Max's attention. (Though later reports seem to indicate the fight had nothing to do with Max, and instead involved sister Ali's purse.)

After the incident, The Wanted showed their support for Lindsay, so it looks like she was returning the favor by supporting them at another gig. Or... she was just trying to get flirty with Max again...

Would Lindsay and Max make a cute couple?
