Nurse!

We're told the "Ghost Rider" star is at the famous Cirque Lodge, near Sundance. The Lodge, which treated Lindsay Lohan and other stars, is one of the most respected treatment facilities in the country.

Eva has been at Cirque for several weeks.

Her rep tells TMZ "Eva has been working hard for the past year and made a positive decision to take some much-needed time off to proactively attend to some personal issues that, while not critical, she felt deserved some outside professional support. Out of respect for Eva's privacy, we do not wish to discuss further details."

Pompeo and her husband were running into a screening when TMZ caught them -- and Pompeo completely stonewalled us. Next time, we'll make an appointment.

Sources at UCLA Medical Center tell TMZ Britney Spears has been classified as "G.D." -- Gravely Disabled. That is a huge and dangerous deal. That means the patient is unable to take care of basic needs, such as the acquisition of food, clothing or shelter. Being G.D. is one of the criteria for involuntary commitment.

Several health care professionals tell us Britney has fallen into a "manic state" due to her bipolar disorder. We're also told she arrived at the hospital this morning at around 2:15 AM, but wasn't admitted until 4:15 AM because she was causing such a scene in the hospital.

We first reported that Britney accused her mother of sleeping with her boyfriend. Now we have more. We're told Britney screamed, "The only reason she's admitting me is because she wants to be alone with her boyfriend! She wants to sleep with my boyfriend!!" Britney never said exactly who she was talking about.

TMZ has learned actor Justin Chambers, Dr. Alex Karev on "Grey's Anatomy," checked himself in to the psych ward at UCLA Medical Center this week. Yes, it's the same place ...

Chambers' rep confirmed to TMZ that star checked in on Monday and checked out yesterday.

The rep claims Chambers, a married father of five, was "exhausted and suffers from a sleeping disorder. He went in voluntarily to get some help."

Chambers was in the same ward where Britney is being treated.

As TMZ first reported, the family is staging an intervention so Britney can get help for her bipolar disorder. Family sources say they are furious at Lutfi, claiming he pushed Brit into going to B.H. Mercedes today to buy a new car -- in the middle of the effort to save her.

One source says the family believes Lutfi has been a "counterproductive, disquieting force" who has done nothing but harm.

Dr. Rey surprisingly acknowledged that vaginal reconstruction is his third most popular procedure. Hollywood sets the pace for cosmetic surgeries -- so get ready America. New boobs are sooo last year!

Donald has a "serious, serious" smoke allergy says the rep, and there are always strict guidelines in place to ensure he's not exposed to secondhand smoke. Just prior to Donald's arrival at the junket, some staff members had been puffin' away on the balcony -- and that just wasn't going to work.

Incidentally, Sutherland's son, "24" star Kiefer, is rarely seen without a cig. TMZ caught Donald hugging his smoky son last week, after Kiefer's release from jail. Perhaps he held his breath.

Sutherland's publicist had no comment on how he manages his extreme allergy around Kiefer.

TMZ has learned that Academy Award red carpet staple Sally Kirkland was hospitalized for exhaustion this weekend, but has since been released.

A rep for Kirkland issued the following statement exclusively to TMZ:

"Ms. Kirkland was admitted to an outpatient hospital for exhaustion and sleep deprivation. She has been treated and released, and thanks her fans for their ongoing support and prayers."

We're told Kirkland, 66, is resting at home after filming three movies back-to-back, is feeling better and will be back to work later this week.

Although "car issues" almost kept Rebecca and her "McSteamy" husband, Eric Dane, from getting to the SAG Awards last night, luckily -- it was just the battery that died.

The doctor, who performed cosmetic surgery on Donda West before she died, said he needed a second chance to defend himself -- even stating that the West family attorney agreed with his decision.

Adams, who referred to himself in the third person, also responded to criticism that he shouldn't be practicing cosmetic surgery without being board certified, and explained his credentials. King invited Dr. Jan back for a full hour.

TMZ tried to get the doctor to say why he operated on Donda West when others had turned her down, but he had no comment.

TMZ has learned that 2006 Academy Award nominee Heath Ledger has died in NY.

He was found dead in his bed in one of his residences in Soho by his housekeeper at 3:35 PM ET today. Law enforcement sources tell TMZ they believe it was not a crime, adding that prescription pills were found near his body.

According to NYPD a masseuse arrived at Ledger's apartment and was let in by a housekeeper. When Ledger didn't answer his bedroom door, the housekeeper and the masseuse opened it and found him unconscious. They attempted to wake him; when they couldn't, they called 911.

We're told when paramedics responded, the actor was in full cardiac arrest. They attempted to perform CPR on him, but were unsuccessful. He was pronounced dead at the scene.

The 28-year-old actor has a two year old daughter with former fiancee Michelle Williams -- they separated in September, 2007. He plays The Joker in the upcoming Batman film, "The Dark Knight" and is perhaps best known for his groundbreaking role as Ennis in "Brokeback Mountain."

Herschel Walker, considered by many to be one of the most dominant players in college football history, is expected to reveal in an upcoming book that he has multiple personalities. "Breaking Free" will be released in August and will document Walker's life with MPD.

TMZ has learned that Christian Brando, the 49-year-old son of actor Marlon, is in bad shape at Hollywood Presbyterian hospital.

Sources tell TMZ that Brando was admitted on Jan. 11 and remains in ICU. The exact nature of his illness is unknown.

Brando was convicted of voluntary manslaughter in the 1990 death of his half-sister's boyfriend, Dag Drollet. Christian got out of prison in 1996.

Since the original incident, it has emerged in reports that Nate actually suffered a stroke, rather than a heart attack. The 38-year-old Dogg cousin is currently in a medical rehabilitation facility recovering from the stroke, after being released from a hospital on December 26 -- no other information on his condition is available.

TMZ has learned that "HSM" star Zac Efron was rushed to Cedars-Sinai Medical Center today suffering from appendicitis.

His rep tells us "He had his appendix removed and is recuperating."
