Is Lindsay losing it? No, for real. I'm worried about her. This is getting too crazy.

LiLo partied at Playhouse in Hollywood and then returned to Sam's place with a gal pal and waited... and waited... for the DJ to arrive home.

From 3 am to 5 am, Linds sat out on the doorsteps, sometimes yelling at her friend and sometimes yelling on the phone. Finally at 5, Sam gets home and asks "who is out here?" to which Lindsay screams: "Um, your girlfriend!" And then the two proceed to fight about where Samantha was, and with who...

Sam asks the gal pal to leave (and call a cab) while she and Linds continue squabbling, and crying, inside the house. Watch it all play out in the vid below:



I've gotta hand it to Samantha - she's being about as sensitive as she can be while still trying to stay strong with her emotionally unstable girlfriend. But how long can their on-and-off relationship really last?
