• Rachel Bilson and Adam Brody, snacking on milk and cookies at L.A.'s Hyde Lounge. "They spent much of the night whispering," says a clubgoer. Nearby, Bilson's The Last Kiss costar Jacinda Barrett and her husband, actor Gabriel Macht, held hands at another table.

• Jennifer Lopez and Marc Anthony, celebrating Anthony's 38th birthday at The Venetian's Tao nightclub. Along with a group of 25 pals (including Leah Remini), the couple feasted on sea bass, Kobe sirloin, lobster wontons and sashimi tuna rolls and then hit the dance floor. When DJ Lucho started spinning the Jackson 5's "I Want You Back," Lopez – wearing a long black dress – and Anthony – in a dapper dark suit – gathered all of their guests in a circle to sing. During Anthony's b-day speech, the singer said he always knew he was lucky but he's even luckier now because he has Lopez as his wife. "They were very close the whole night, obviously into each other," says a source. "They were very cute and affectionate."
