Christina Aguilera and fellow pop star Pink had a wild time at Pink's decadent 22nd birthday party in New York, according to the PAGE SIX column in the New York Post.

Some amorous action unfolded between the two at the downtown dance club Eden during a 3:30 a.m. game of spin-the-bottle after most of the revelers, including Lil' Kim, L.A. Reid and Patricia Field, had called it a night.

"Pink was naked from the waist up, wearing only body paint," the PAGE SIX item says, quoting an inside source. "She spun the bottle and it landed on Christina, and she leaned over and kissed Christina right on the lips."

Aguilera then pointed the bottle at dancer boyfriend Jorge Santos, and the couple promptly engaged in a torrid tongue-wrestling match. Christina's smooch sessions capped off a wild night that included a trio of drag queens belting out Destiny's Child songs and a topless Pink smashing a condom-filled pinata.

Meanwhile, at Sean "Puffy" Combs' record-release party at the Tao club, a procession of macho hip-hoppers – including Puffy and his beefy entourage, LL Cool J and Ice-T – came face to face with a gaggle of effeminate gay guys on the red carpet.

The encounter happened because the curtain hung as a photo background on the East 58th Street sidewalk was right next to The Wall, a popular gay bar two doors down.

"All these twinkie little Asian guys trying to get into The Wall were running into these macho rappers on the red carpet," said a party organizer, according to the story in PAGE SIX.

"Finally, we had to cut a hole around the door of The Wall and post a security guard outside so these guys could get inside their club. Just think, if Puffy had taken a wrong turn outside, he could have ended up in a gay bar!" (TRJ)
