LAS VEGAS -- The party vibe established at MTV’s Video Music Awards continued long after the last moon-man trophy was presented.

Post-show soirees all over town boasted star-studded guest lists, plus long lines and crowds of camera-toting fans hoping to snap shots of their favorite celebs.

For many show guests and workers, the first stop was the poolside party at the Palms, site of the awards presentation.  Hosted by Jamie Foxx and Jennifer Garner, the “official” post-show event promised an open bar and an ample buffet.

Foxx was gregarious, dancing and rapping on stage as he poured fruity shots from a bottle directly into the mouths of thirsty women. He was briefly joined by Quincy Jones, who sipped from a pink drink as he boogied alongside a bevy of beauties.

Meanwhile, at the Wynn hotel’s Blush nightclub, fans lined a red carpet that welcomed Pamela Anderson, Dr. Dre and Robin Thicke, who celebrated in a roped-off area that spared them from the club’s crowd.

Janet Jackson and beau Jermaine Dupri partied at Tao, along with T.I., Nelly and Travis Barker.

Sean “Diddy” Combs hosted a capacity crowd at Luxor’s week-old nightclub, LAX. It was so packed that the staircase leading down to the dance floor was declared off-limits. Most late-arriving guests had to stay upstairs—except for one. Paris Hilton popped in just after 2 a.m. Monday and a trio of security guards immediately whisked her downstairs, straight to the dance floor.
