• Beyoncé and Jay-Z, feasting at a dinner the hip-hop mogul cohosted with NBA star LeBron James at the Tao Nightclub at the Venetian. Also making the scene: Christina Aguilera and husband Jordan Bratman, Sean "Diddy" Combs and Kelly Rowland.

• Paris Hilton, celebrating her 26th birthday at the Body English nightclub at the Hard Rock Hotel and Casino with on-again beau Stavros Niarchos, sister Nicky, her boyfriend David Katzenberg and pal Brody Jenner. When Prince's song "Kiss" began playing, the birthday girl – who got a congratulatory shout-out over the loudspeaker from the deejay – started rocking out. She then took her crew to the bowling alley at 3 a.m.

• Whitney Houston and Ray J, holding hands as they walked into the Budweiser and Sprite party at Tao. The duo was seen leaving immediately after Ray J ex Kim Kardashian arrived.

• Ludacris, telling Queen Latifah how happy he was about his recent Grammy win at Zo and Magic's 8-Ball Challenge pool tournament, which the hip-hop stars hosted at Wynn Las Vegas (proceeds benefited the Alonzo Mourning Charities for underprivileged children and The Magic Johnson Foundation). Nick Cannon deejayed the event and Gabrielle Union, Shaquille O'Neal and others made the scene.

More Celeb Spotting

• Mario Lopez and his Dancing with the Stars partner Karina Smirnoff, kissing, bumping-and-grinding and whispering in each other's ears at the new Revolution club at the Mirage Hotel and Casino. Also making the scene: Joel Madden, who deejayed a set of hip-hop and mashups, and 50 Cent, who ordered rounds of cognac as he held court in a back corner with his entourage.

• David Arquette, leading his West team to a 40-21 victory over Chris Tucker's East team at the McDonald's Celebrity Game at the Mandalay Bay. Jamie Foxx and Nelly also hit the court and CaCee Cobb cheered on her man Donald Faison from the stands.

• Diddy, downing Patrón shots at his Black-Tie Affair bash at Rain at the Palms hotel. "Ain't nobody do it the way we do it," he told the crowd over the loudspeakers, from his perch in the VIP section of the 25,000-sq-ft. club, which features a moat around the dance floor and machines that project fire above the dance floor. "You better not hold back. Take your shirt off. Take your panties off. This is Bad Boy (Records)!" At 2 a.m., the fire marshal showed up and stopped partygoers from entering the already-packed bash.

• Eva Longoria and four pals getting facial treatments at Caesars Palace's Qua spa in preparation for her and fiancé Tony Parker's bash that night at Pure Nightclub. Also partying with the engaged couple: Cameron Diaz, who danced the night away with Rosie Perez and drank Chardonnay.
