Prince Frederic Von Anhalt has been diagnosed with shingles.
Zsa Zsa Gabour’s husband sought medical advice on Thursday (18Aug11) after he began feeling unwell and his face started to swell - and the condition stems from a childhood illness.
He tells TMZ.com, "The chickenpox I had when I was eight years old has returned and the virus gave me shingles."
It's the latest in a string of health worries for the couple - Gabor has been in and out of hospital since she broke her hip in a fall last summer (10) and in January (11), part of her leg was amputated to stop the spread of gangrene.
The couple celebrated their 25th Wedding anniversary earlier this week.
