Did Lindsanity Forget That Her Sister Is Only 16????

Surprise, surprise!

LOLhan brought along 16-year-old sister Ali while pAArtying in El Lay on Friday night!

Such a fine role model, that Linds.

The sisters Lohan first hit up one of Lindsanity’s old haunts, Teddy’s, where spies say they saw Ali wearing solely a vest as a shirt paired with some booty shorts.

Slutty!

The two spent the night “dancing wildly” while LOLhan chain smoked inside the lounge.

Dirty, dirty.

Ali and Lindsay then ran into How I Met Your Mother star Jason Segel while at Teddy’s, and the three took off for Maroon 5 frontman Adam Levine‘s Hollywood pad, where they all pAArtied until 6 AM!

(Sniff sniff.)

One question: where was Dina????
