SCRAM can't stop LiLo from staying out as late as she wants!

The quintessential night owl, troubled starlet Lindsay Lohan, enjoyed a busy Saturday night as usual... only this time around, she brought her little sister Ali!

After a sexy photo shoot in the 'Bu, Linds next showed up to the Chateau Marmont around 11 pm and stayed until 1:40 am. Then it was off to a friend's house party in Larchmont where she and Ali stayed until 3:30 am.

I know Ali is 16, never seems to go to school (it's summer now, but whatever!) and basically just follows Linds around wherever she goes, but still... can one of them please start getting to bed at a reasonable hour? Maybe 2 am?
