Lindsay Lohan isn't letting that pesky little legal problem in L.A. get in the way of a good time. The Mean Girls star was spotted at the Coachella Music Festival on Friday.

She was all smiles -- catch those inflated lips! -- when she was photographed with some friends.

As Breaking Celebrity News has been reporting, the Los Angeles County Sheriff's Department is investigating allegations that LiLo assaulted a woman at the Standard Hotel last Saturday.

Lohan joined a bevy of other stars including Vanessa Hudgens, Paris Hilton, Pierce Brosnan and Kate Bosworth at the annual music fest.

It's one of her MUST destinations every April.
