Brit to Nanny -- Sleep with Me and the Boys!

In yet another shocking twist with the help, Britney Spears once asked a nanny to sleep with her – and her infant sons – in the same bed. Just how we did it back home, ya'll!

That's just one of the eyebrow-raising allegations made by ex-nannies to Us, as Kevin Federline rounds up all of Britney's former help – and there's plenty of 'em – and their Britney-bad-mommy stories. What else? "She'll strip down in front of staff, nannies, whomever," said one source. "She'll ask, 'Do I look sexy? Do I look pretty? She's extremely insecure."

And as for her hiring criteria, actual child-care experience doesn't seem to be overly important. "She just cares about whether they're young and fun and like to drink and party," says an Us source.

Mayer and Diaz – Big Apple Boom-Boom?

We all wondered whether John Mayer and Mandy Moore were an item after they were spied having lunch in Manhattan on Tuesday. Looks like John moved on pretty quick – now the buzz is that Cameron Diaz is in the former Simpson-boytoy's sights. Page Six reports that the pair had dinner at downtown's Indochine, and that they were "very playful and cozy," and "lingered over dessert."

Cam, of course, is cavorting with the rocker in the (very near) shadow of her ex-longtime-boyfriend Justin Timberlake, who's performing at Madison Square Garden this week. The couple's reps didn't comment.

L.C. – Those Bitchfights Are So Real!

The claws are clearly out on this season of "The Hills" between L.C. and Heidi – and Lauren, at least, says their razor-sharpness isn't just for the cameras.

It all started, of course, when the formerly mousy Montag allegedly started spreading the rumors that Conrad had made a sex tape with her ex, Jason Wahler. But now, said Conrad to Ryan Seacrest on his KIIS-FM show (via People), a post-boob-job Heidi "not the same person anymore ... I feel like I don't even know [her]." And L.C. smashes any hope of a Hilton-Richie-style détente: "I don't think so ... Probably not. I can see us getting to not hating each other."

Party Favors: Halle Berry Not Pregnant, Part MXVIII ... Obama Rocks Tyra ... Tinz and Olivia Think Idiotic Feud More Important than Darfur Victims

Yet another official debunk in the Halle Berry baby-bump watch comes today courtesy of VH1's, which quotes Halle's manager calling a tabloid report that she's two months preggers "not true." ... Talk mostest Tyra Banks will get her way with White House hopeful Sen. Barack Obama when he appears on her show September 27 to discuss his run for the Presidency. No word on whether Banks will pursue a similar line of inquiry as when Katharine McPhee was on. ... Today's outlet for outrage comes courtesy of New York imbecil-ites Tinsley Mortimer and Olivia Palermo, whom Page Six says wouldn't show up at a benefit for Darfur genocide victims after they found out the other was going to be there. Brooke Astor rolling in her grave, indeed.
