• Talk about some A-list musical guests! After their concert in London,
the Black Eyed Peas threw a Bacardi-sponsored afterparty at indigoO2 –
and they were joined on stage by Tom Cruise and Katie Holmes. The actor performed a duet with will.i.am called "Some Day," from his upcoming movie Knight and Day, while his wife salsa danced with Fergie.
"It was unreal," a source says. "Everyone was going crazy." Later in
the evening, the actors got cozy on the dancefloor. "They were all over
each other," the source says, "giggling and dancing all night."


• Matt Lauer and wife Annette
were spotted having a double date at Le Caprice, the restaurant inside
New York's Pierre Hotel. The two couples were deep in conversation
throughout the night, sharing bites of their entrees and enjoying some
wine. According to a source, the Today show host was especially in high spirits.


• After sunning themselves on a daybed and swilling poolside mojitos at Las Vegas's Tao Beach's Memorial Day bash, Mark Ballas had a late-night dinner at Lavo with Ashley Roberts – and the cozy couple wasn't alone. The Dancing with the Stars pro's dad, Corky,
shared the meal with them. After dinner, Corky showed off some tango
moves in the dining room before the three headed over to the nightclub.
Across the way, Forest Whitaker was dining with wife Keisha and a producer friend. The trio was greeted at one point during their meal by Stacy Keibler, who came to say hello.


• Also in Sin City: Jenna Jameson and hubby Tito Ortiz, who were spotted at the Hard Rock Hotel and Casino, where they took in the UFC afterparty at Vanity nightclub.
