Zsa Zsa Gabor was rushed back to hospital today (02.03.11) because of circulation problems in her left leg.

The ailing actress - who had part of her right leg amputated in January after gangrene set in - was brought from her Beverly Hills mansion to Los Angeles' Ronald Reagan UCLA Medical Centre by ambulance at 11am after her personal physician discovered a lack of blood flowing through her left leg during a routine check-up.

Zsa Zsa's husband Prince Frederic von Anhalt told the Los Angeles Times: "We are at the emergency room and the doctors are checking her out right now."

Zsa Zsa - who has been married seven times - has been in and out of hospital since suffering from two blood clots following hip surgery last July, and was even read her last rites by a priest in November.

She was released from hospital last month in order to celebrate her 94th birthday at home surrounded by friends and family.

Her publicist John Blanchette revealed doctors worked hard to have her ready to leave hospital for the celebrations, saying: "They did a magnificent job getting her back. They treated her with an aggressive treatment of antibiotics. The doctors said it was 50-50, but it worked.

"This has been a long, tough road since 2002, when she had an accident that originally disabled her. She has never been able to walk and her health has spiralled down.

"But she has kept her sense of humour and she's a fighter. She always has been."
