Couples Watch | Kate Hudson, Owen Wilson
Kate Hudson and Owen Wilson, nuzzling one another and sharing a "kiss on the lips" at Hollywood hot spot Les Deux, a source tells us. The normally PDA-shy duo perched on a couch together, with Hudson sitting cross-legged next to Wilson while drinking cocktails and smoking cigarettes. Also making the scene: Jeremy Piven, who hung out with friends (including Maroon 5 frontman Adam Levine) at the table next to them, and Mary-Kate Olsen, who sat nearby and sang along to just about every song that played. A couple of days earlier, new couple Brody Jenner and Lauren Conrad were at the club being "touchy-feely."

Drew Barrymore and beau Fabrizio Moretti, rocking out at the Bob Dylan concert at L.A.'s The Forum. Later, they partied together at West Hollywood hotel Sunset Marquis. While they were cuddling on the poolside chairs, a hotel employee informed them that the pool area was closed. Though they were surprised, they obliged and headed to the bar.

Paris Hilton and Travis Barker, "talking in hushed tones" at L.A.'s Hyde Lounge. After chilling with pals including Kim Kardashian and Nick Cannon, the duo "left together hand-in-hand," says a patron. Ironically, the lounge is the same spot where Hilton and Barker's ex Shanna Moakler had their infamous dustup. Also cozying up: CaCee Cobb and Donald Faison. "They were exchanging smooches," says an onlooker. On another night, Ashley Olsen and boyfriend Greg Chait nibbled on wasabi peas and held hands in a booth as they partied with Mary-Kate. "They were having a wonderful time, whispering and snuggling," says an onlooker.
