Lindsay was just sentenced to a 90 day locked rehab facility, so she should really be focusing on getting her life on track.

That might be hard to do, since her new boyfriend is a NYC CLUB PROMOTER!

Rumor is - Lindsay is dating a guy named Avi Snow (who also plays guitar for a band called City of the Sun).

Let's hope he keeps her on the right path and she doesn't take advantage of his "connections".
