Gossip-philes in the D.C. area might want to head over to LUX Lounge tonight for a potential celebrity sighting. L.A. DJ slash Lindsay Lohan girlfriend Samantha Ronson is guest DJing at the Mt. Vernon Triangle club tonight, and it’s possible the queen of rehab herself will be in tow—she’s often spotted hanging around Ronson’s gigs guzzling Red Bull and grooving to her gf’s beats. We’re kind of surprised to see Sam and Lindsay back in town so soon, however, after Ronson’s November appearance at another D.C. club—especially since during that visit, paparazzi caught Lindsay on camera falling off the wagon up in the DJ booth, vodka cocktail in hand. If you can’t be bothered to show up tonight, you can always check in to see what went down on Lohan’s blog tomorrow.
