Zsa Zsa GaborZsa Zsa Gabor, ailing since summer 2010, will have three-quarters of her right leg amputated by a Los Angeles doctor today, RadarOnline.com reports.

Publicist John Blanchette tells Radar the surgery was scheduled to take place at 11AM PST at Ronald Reagan UCLA Medical Center. An infected bone in 93-year-old Zsa Zsa's leg necessitated the procedure.

Blanchette says a press conference will be held shortly after the operation, which is expected to last an hour. Prince Frederic von Anhalt, Gabor's husband since 1986, is at the hospital.
