She is survived by her ninth husband, Frédéric Prinz von Anhalt.

Born on February 6, 1917 in Budapest, Gabor was crowned Miss Hungary in 1936, before moving to the US in 1941.

A true Hollywood icon, Gabor became a socialite alongside her sister Eva in Beverly Hills.

Despite having a number of film roles, including a lead in Moulin Rouge (1952), Gabor was always better known for her personal life than her professional one.

She was married nine times. The first seven ended in divorce, while the eighth, to Mexican actor Felipe de Alba, lasted a single day, ending in an annulment after it was realised Gabor's seventh marriage had not been legally ended.

She was once quoted as saying, "I am a marvellous housekeeper: Every time I leave a man I keep his house."

Gabor's only child, Francesca Hilton, whose father Conrad Hilton is the founder of the Hilton Hotels chain, passed away last year after suffering a stroke, aged 67.

According to the Hollywood Reporter, Hilton had been feuding's with her mother's ninth and current husband, Frederic Prinz von Anhalt, whom Gabor married in 1986.

The feud was reportedly over access to her mother who the Reporter said Hilton's publicist described as "suffering total dementia" and unable to speak, as well as family finances.
