Lindsay Lohan finishes up her house arrest in Los Angeles on Wednesday, but her social calendar is already filling up. The troubled actress turns 25 on July 2, and according to one source, she plans to celebrate at a star-studded bash this Saturday in Southampton, N.Y.

 

She wastes no time, huh? So what does her rep have to say about this possible party? Her spokesperson Steve Honig tells me: "We're choosing to let Lindsay celebrate her birthday with family and friends privately."

 

He declined to comment on whether she'd be in New York or California come Saturday, but an events calendar has Lindsay on the guest list for the L.A. Takes Over the Hamptons fete, held at a private residence. Also slated to attend? Paul and Chloe Sevigny, Liv Tyler and ... Samantha Ronson? It should be one interesting soiree if all of them actually show up. One thing's for sure: LiLo is an Empire State of mind these days. "i really miss nyc... home! Along with all of my family and friends in it!!! esp. @ mikelohan," she tweeted last week. "i'm jealous too... i want to be in nyc :(," she wrote on Monday. If she does indeed hit the Hamptons, we'll keep you posted. Wherever she celebrates, let's hope this one doesn't pack a punch. She supposedly got socked by a waitress during her B-day festivities in L.A. last year.
