Lindsay's Back To Partying! - Now With VIDEO!

Could this be the new terrible trio set to tear up Hollywood? Lindsay, Paris, and Brittny Gastineau hit up Villa last night and here's what our Girl X17, who was inside the club, told me last night by email:

Ok - so Lindsay Lohan was partying with Paris, Courtenay Semel, and Brittny Gastineau. Lindsay Lohan was drinking vodka cocktails. Several of them ... she wasn't drunk but she was having fun talking and dancing and laughing and unfortunately she is not sober anymore. I know for sure. Trust me. She showed up under the radar at around 10:45pm and left a little after midnight. They were all sitting at the same table having a blast.

Watch out, Linds! Remember what you learned in Utah!
