Lindsay's New Girl: Brittny Gastineau!?

Woah...we know Lindsay has a lot of party buddies friends in Hollywood, but we never would have put her with socialite/D-lister Brittny Gastineau!

Lindsay and Brittny started off their evening by leaving Lilo's pad around midnight, and they headed to Nobu, where they stayed until 1:10am. While most of us were fast asleep, Lilo and Britt bounced over to club MyHouse, where they partied until 2:20am. The girls left in a crowded car, which drove around Samantha Ronson's house and neighborhood for half an hour. Hmm, desperate much? It looks like the persistence (and perhaps flaunting Britt) paid off though, because around 4am, Lindsay returned to Sam's house and after a fair amount of begging, she was let in. Or maybe Sam didn't want her to cause a scene?

While this could just be an innocent night out on the town for Linds and Britt, we have to wonder if there was something going on between the ladies, and if night's shenanigans were an attempt to make Samantha jealous. You see, Brittny supposedly dated Backstreet Boy Nick Carter several years ago, but she's very good friends with Courtenaaay Semel (Lindsay's rumored first lesbian love) and last year, she was snapped going to a lesbian nightclub with Paris Hilton. While we're not claiming she plays for the same team as Lilo, we certainly have to wonder if these two are more than just girlfriends!

What do you think is going on here? Is Lindsay trying to piss off Sam, or is she merely hanging out with a new (platonic) gal pal?
