Britney Drops Dime in Rehab

Looks like rehab did more than good for Britney Spears' soul – she also dropped a surprising ten pounds during her stay in Promises, and got herself not just buff, but buffed with spa treatments.

That Other Blog tells us this morning that the pop princess lost at least 10 lbs. during her stay at Promises – a figure that's backed up by snaps from the weekend, which TMZ showed you yesterday. What's more, adds TOB, while inside she was treated to several spa treatments that included skin cleansing, helping to release toxins from her system.

And as TMZ's been told, Britney's made a real and significant turnaround since she checked in to the Malibu rehab facility.

Eminem and Ex-Wife Agree to Shut Up

Now this, folks, is real news. Eminem and his ex-wife Kim Mathers actually agreed not to trash each other in public – for the sake of their daughter. The couple made the decision during a court hearing in Michigan after Eminem (aka Marshall Mathers) filed a motion Friday to muzzle Kim, after she'd made numerous salacious comments about the rapper. Kim had told one TV interviewer that she'd been driven to attempt suicide by Eminem, and recently told a Detroit radio station that he was unfaithful and uncaring and said some uncomplimentary things about his sexual athleticism. Eminem didn't actually appear in court, except by phone, and his lawyer said, "We're happy the court was able to bring this matter to a just and equitable resolution."

Piven Gets Pissy, Again

Jeremy Piven may need to learn how to cook for himself pretty soon, as he's getting the ol' 86 from a growing slew of eateries. The "Entourage" star got into a tiff, reports Ben Widdicombe of the New York Daily News, with a hostess at an unnamed restaurant off Vine in Hollywood. It seems that Piven tried to get into the joint on Valentine's Day without a reservation, but when the hostess explained that they were booked solid, Jeremy exploded. "Believe it or not, he used the 'Don't you know who I am?' line," says Widdicombe's source. And then he got all Ari Gold on the hostess, humiliating her for working in a restaurant. This incident follows on allegations that Piven's been banned from Nobu restaurants across the world for his boorish behavior at the Aspen branch.

Remember when Jessica Simpson won a Chrysler Crossfire last fall and everyone was, like, "What does she need with a new car?" Well, turns out Jessica is giving it to someone who really needs it.
