Prince Frederic von Anhalt, who has been married to the Hungarian-born actress for 24 years, had to receive emergency medical treatment at a Beverly Hills clinic after mistaking nail glue for eye drops and must now wear a patch for two weeks. The couple`s publicist John Blanchette said: "It was dark and he grabbed his wife`s nail glue instead of eye drops." Prince Frederic added: "It was stupid. She doesn`t use it anymore." This is not the first time the 66-year-old German socialite - who is 93-year-old Zsa Zsa`s ninth husband - has been hospitalised with a bizarre injury in recent months. In October, he needed medical assistance after accidentally swallowing a bee, which stung the inside of his throat. Zsa Zsa has been plagued with ill health this year after falling out of bed and undergoing a hip replacement operation in July. At one point, a priest was called in to read the star her last rites. Prince Frederick has previously revealed he wants his wife`s body to be plastinated and put on show when she dies so her beauty will last forever. He said: "My wife has always dreamt that her beauty would be immortal. I would like to show the plastinated body of Zsa Zsa Gabor in the context of a scene in one of her films."
