The Hungarian-born star of 1950s movies "Moulin Rouge" and "Touch of Evil" spent five days in the hospital, in this latest round of treatment. Before Gabor left Ronald Reagan UCLA Medical Center in Los Angeles on Sunday to return to her palatial house, doctors and nurses sang happy birthday, said publicist John Blanchette.

Her friend, the singer Engelbert Humperdink, was expected to attend the party at Gabor's house and serenade the birthday girl, Blanchette said. Gabor, who was a fixture of Hollywood's social scene, suffered a stroke in 2005, and this past July she had hip replacement surgery. She also had her leg amputated last month because of a gangrene infection.
