Last night Brittny Gastineau had her birthday bash at Beso, and later she moved the party to Crown Bar, where none other than Lindsay Lohan showed up!

Our fav rehabber snuck out the back of the club around 2:20am by herself, and our X17 photographer on the scene tells us Linds was "hanging out in the back alley drinking from a cup and crying. It was obvious that she was upset about something, and as soon as she saw photographers she tried to cover her face."

We can't imagine what set Lilo off, and while she doesn't look like a happy camper here, we're def digging her outfit. Girlfriend may be a hot mess, but she always nails it in the fashion department - cheer up Lilo, that's something to be happy about!

Soo, what was she drinking?
