When we caught Lindsay Lohan sneaking her teenage (and WAY underage) sister Ali into Crown Bar the other day, we got a bit worried, and it looks like we weren't the only ones!

An insider at the club tells L&S, "I couldn’t believe Ali was there. They partied until after 1am, and she treated Ali as if she were just one of her friends at the club with her. And Ali was excited to be there. She loved being out on the scene with her sister. It was as if she knew she belonged there.”

The mag claims Lindsay has exposed Ali to drugs and plastic surgery, and a source close to the Lohans adds, "Anything Lindsay does, Ali wants to do." Hmm, but did Ali really get her lips done? Or is she just sharing Lindsay's miracle lip gloss?
