Kevin Federline ran into Paris and Nicky Hilton last night at Club LAX in Las Vegas. In between chats with Paris, Kevin took to the stage for some impromptu “rapping,”while Paris and her man-hands danced on a banquette like an idiot.

Paris was in town to host the New Year’s Eve party at Luxor. No word if Kevin is invited to that shindig.

Despite the Daily Mail’s report that Nicole Kidman announced her pregnancy to family over the Christmas holiday, the actress’ rep claimed the report is incorrect.

“It is incorrect. She must have had about 30 babies by now.”

As for Kidman, says the rep, “She’s in Australia making a film,” director Baz Luhrman’s epic Australia, costarring Hugh Jackman, “and her family are in Australia. She’s happily ensconced away somewhere having a few days break. It’s the silly season. As far as we’re concerned, it’s another rumor out of London.”

Still, a friend said it’s “conceivable” that Nicole and husband Keith Urban could be expecting their first child together.

“She did have a small baby bump a month ago, so it would be reasonable that she’d now be three months and telling her friends and family.”

Nicole also has two adopted children, Isabella, 14, and Connor, 12, with ex-husband Tom Cruise.

Entertainment Tonight scored the first photos of Jamie Lynn Spears, post-pregnancy announcement. The 16 year old and her baby-daddy, Casey Aldridge, managed to keep a low profile since Jamie Lynn’s OK! Magazine cover hit stands last week, but cameras caught up with the couple over the weekend.

Jamie Lynn is approximately 13 weeks pregnant, but doesn’t appear to be showing yet.

Mary-Kate Olsen and a male friend hit up a Los Angeles liquor store this weekend for a case of Corona. No champagne at MK’s New Year’s Eve party: she’s keeping it real, just like any other impoverished 21 year old.

Congrats to Jimmy Fallon: the former SNL star married girlfriend Nancy Juvonen on Saturday in the Caribbean’s Necker Island. According to their rep, the couple “had family and close friends in attendance” at the ceremony.

It was the first marriage for both.
