On Friday nights, European-style lounge Les Deux is one of L.A.'s hippest hot spots. With candelabras lighting the peach-and-black rooms, and sexy red leather booths inside and a tree-lined cobblestone terrace outside, the mood is set for its celebrity guests.

One recent evening, Leonardo DiCaprio chilled outside in a candle-lit booth as a water fountain bubbled in the center of the patio. Nearby, Lindsay Lohan held court atop a banquette and chatted with pals including Maroon 5 singer Adam Levine as a classic foreign film was projected on one of the terrace's walls.

At another table, Mary-Kate Olsen and a female friend chatted with Matthew Perry while O.C. stars Benjamin McKenzie and Rachel Bilson hung out with pals.

Meanwhile, inside, Christina Aguilera lounged in a VIP booth with husband Jordan Bratman and friends. They snacked on strawberries, tarts and mini-cupcakes. And in true star fashion, even when her hit song "Ain't No Other Man" got people in the room grooving, the singer didn't even blink.
