X17 XCLUSIVE - Samantha Throws Lindsay And Her Clothes Out The Door At 6am!

Well, she certainly tried to!

Yesterday evening Lindsay Lohan went shopping at Urban Outfitters on Melrose, and a little bit later we snapped Samantha at Nobu in Malibu with gal pal Drea de Matteo. After dinner with Drea (and presumably grabbing some drinks), we didn't catch Sam returning home until 5am, and she had a huuuge grin on her face. We're guessing her smile disappeared when Lindsay showed up around 6am, because photographers outside could hear the girls screeching at each other, and shortly after that, Samantha was seen tossing a bag of Lindsay's clothes out the door in an attempt to kick her out! X17 photogs tells X17online exclusively:

"Lindsay looked very embarrassed when she was banging on Samantha's door this morning. From what we could hear, the girls were fighting about Sam going to dinner with Drea [de Matteo] last night, and even though it didn't appear to be a romantic date, Lindsay seemed to think it was, and she was screaming at Sam."

We know it doesn't take much to send Lindsay over the edge, but does she have a reason to be jealous of Drea? Or is she being totally delusional?
