Lindsay Lohan lindssamwhyfight.jpg

And more importantly, are they still?

LiLo and S.Ro are holed up together until tomorrow (most likely) and, arrest warrants aside, we can't help but wonder why they fought in the first place and how the window got broken...

Hmm, let's break it down: Lindsay was hanging out with a mystery girl the day before the drama began - maybe something related to that? Or maybe Sam was mad Linds was partying at Jack Nicholson’s house Friday night with other girls (and binging during her absence)? On the other hand, Linds could've been upset that Samantha left her behind (again) when she went to Calgary for a dj gig on Friday, right?

So many possibilities!

What do you think is the reason behind the squabble?
