Exclusive Details

TMZ has learned Mariska Hargitay's suffered a partially collapsed lung over the Xmas holiday and it collapsed again today.

Her rep only would confirm that a partially collapsed lung has sidelined the actress.

We're told she has been readmitted to the hospital but will not miss any episodes. We do not know her condition.

Hargitay was sledding in the Hamptons around New Year's Eve but we're now told the cause of the lung problem is unknown.

A hugely expensive bracelet on loan to Winona Ryder has gone missing in Spain, but it's Winona who feels like the victim.

Here's the lowdown. Winona was in Madrid Sunday for a Marie Claire event. Marie Claire had given Winona a Bulgari bracelet and a ring to wear, worth $125,000. She also got a dress, shoes and some other stuff to wear to the shindig.

After Winona left Madrid, the bracelet and ring turned up missing. There's a report in a French magazine saying Winona claimed she went to the front desk at the hotel and gave the jewelry to the front desk, but the surveillance cam doesn't show her doing that. The intimation -- Winona stole the bling.

In fact, we know what happened. The morning after the event, around 6:00 AM, Winona checked out of the hotel. No one from Marie Claire was around to collect the stuff, so she left everything in her hotel room.

Our sources confirm the bracelet and ring did indeed turn up missing -- the dress and other stuff weren't taken. We're told Winona never said she had taken the jewels to the front desk, and whoever planted the story may be covering up for someone who had access to the room after she left.

Tina, meet Sarah. Sarah, this is Tina.

Here's what we know about Sarah Palin's scheduled appearance on "Saturday Night Live" tomorrow night. The wannabe VP will appear aside her doppelgänger, Tina Fey, in a sketch -- but so far, it hasn't been written yet.

Although people are speculating host Josh Brolin would appear with Palin as George W. Bush, as of now....no W-themed sketch planned.

Turns out the lady who incubated Ricky Martin's babies is a serial surrogate -- but that doesn't mean she'll squirt 'em out for just anybody.

Sources tell TMZ the 26-year-old mother works for an agency that hooks up surrogates, and Ricky's bambinos are her third surrogate (and second set of twins) -- but she says her womb isn't open to Britney Spears or Michael Jackson. Wonder why ...

We're told before the birth, the two only met a couple of times, and contact with Mr. Loca was mostly through phone and email.

According to law enforcement sources, things got violent around Atlanta's Club Dream when patrons heard that members of the private security team were double charging people to get into the VIP area -- where stars like Usher, Diddy and Nelly were partying.

Cops say pushing and shoving broke out, and as the masses were being thrown outside, that's when a shot rang out. A security guard was treated for a shot in the arm, but has already been released from the hospital.

The incident occurred during a wrap party for Oliver Stone's movie "W" about the Prez. Local station KTBS reports and TMZ sources say Wright, who plays Colin Powell, was repeatedly tasered and pepper sprayed as he lay prone on his stomach in the street. We know witnesses heard the officers using extremely foul language, including the "N" word, directed at Wright.

Our sources say Brolin was observed by witnesses attempting to make peace and standing still as he was repeatedly sprayed in the eyes by cops.

Lee Grivas, the 26-year-old boyfriend of Christina Applegate, was found dead in his apartment.

His body was discovered on July 1 by a neighbor who found him in the living room of his Hollywood apartment. Grivas was pronounced dead at 5:25 PM.

Although the autopsy has not been completed, we're told there were no visible signs of trauma.

Applegate and Grivas dated on and off for years after the pair met through a dancer in her Broadway show "Sweet Charity."
