Prince Frederic von Anhalt hospitalised

Zsa Zsa Gabor's husband has been hospitalised after collapsing while visiting his wife at Ronald Reagan UCLA medical centre.

Prince Frederic von Anhalt - the seventh husband of the 93-year-old screen legend - was admitted to the same facility as the actress on Tuesday after he passed out in an elevator and spent yesterday resting at the hospital, according to the couple's publicist John Blanchette.

He added the pair are being treated in separate rooms.

This is the latest setback for the couple after Zsa Zsa - who had part of her right leg amputated last month when gangrene set in - was rushed back to hospital earlier this week after she started violently spitting up blood.

The actress 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.

Meanwhile, Zsa Zsa's only daughter Constance 'Francesca' Hilton is reportedly preparing to launch a legal battle against Frederic, 67, over her mother's vast estate after he put the ailing actress' 26-room home up for sale.

A source told gossip website PopEater: "Frederic has put Zsa Zsa's Bel Air mansion on the market, but Francesca insists he has no right to sell the property .He signed a prenuptial agreement before marrying Gabor.

"Francesca has had a long and terrible relationship with her stepfather and is terrified that as her mother lies back in a hospital bed he will convince her to sign something that would leave her with nothing. She doesn't trust this man and is very worried about her mother."
