Pete Doherty's time in rehab apparently isn't just about self-help. The London Sun claims the substance-susceptible rocker "shocked patients" at The Priory facility last Sunday by engaging in an al fresco makeout session with persistent squeeze Kate Moss. "They were kissing and groping each other," a mole alleges to the tab. "Hands were going up clothing and there was lots of groaning. They were practically having full-blown ..." Well, you get the idea. But it seems that as soon as the purportedly marriage-minded pair was spotted by a nearby therapy group, they beat a hasty retreat.

The Kate Hudson-Owen Wilson sightings continue. On the heels of reports that the "You, Me and Dupree" co-stars recently spent quality time together in Hawaii comes word from Us Weekly that they cozied up during a Sept. 15 outing to Chateau Marmont in Los Angeles. Kate reportedly arrived with a trio of girlfriends, with Owen turning up -- and offering her a peck on the cheek -- a short time later. "She was so happy to see him!" an excited eyewitness tells the mag. "They gave each other their undivided attention." After some ear-whispering, knee-to-knee touching and snapshot-sharing (the actress displayed pics on her digital camera), the group headed to hot spot Les Deux, where the tousle-tressed twosome openly "flirted," says Us. "They smiled the entire time," recalls a spy. "They didn't care who saw."

Most 18-year-old boys only fantasize -- a lot -- about the girls in Playboy. Aaron Carter plans to marry one. In a move that has "ill-fated first marriage" written all over it, the baby-faced singer has asked Playmate Kari Ann Peniche, 22, who previously dated his big brother Nick (we know, we know), to be his wife, reports People. Carter made his misguided proposal Saturday in Las Vegas in that most romantic of settings, onstage in front of 200 people during a Playboy show at the Palms Casino. "I'm very excited about it," Peniche gushes to People. "Aaron is the most genuine person I know. He's kind, loving, and I love him so much." Carter, who was once the inexplicable center of a Lindsay Lohan-Hilary Duff love triangle, is looking to make things legal with Peniche in the next six months.

Has Lance Armstrong found time to do some dating in between hanging out and working out with bestest pals Matthew McConaughey and Jake Gyllenhaal? Us reports the two-wheeling champ, 35, is seeing actress Brittany Daniel, 30. "It's not serious," a snitch tells the mag. Insists Daniel, "We're just friends."

When it comes to women, Jack Nicholson is an equal opportunity wooer. "In terms of age, you could say that over the last year, I've probably covered the territory from 21 to 61," the almost septuagenarian skirt-chaser admits to Rolling Stone. Still, he says, "I am not obsessed," adding that age has taken a toll on his lady-killing ways. "Whether you want it to or not," sighs Jack, "that part of your life changes."
