Teen idol Eddie Fisher had a secret affair with a real-life princess — the Queen’s sister, Margaret!
The shocking relationship was revealed by the singer’s daughter, “Star Wars” actress Carrie Fisher, 59.
Eddie “had sex” with Margaret, outspoken Carrie dished on a chat show — adding that the pair had a “beautiful” romance!
They apparently hooked up in 1952 when Margaret was 22 and Eddie, 24, had scored his first U.K. No. 1 hit, “Outside of Heaven.”
Over the years, they both became infamous for their sexual conquests.
Princess Margaret’s other celebrity trysts included Peter O’Toole, David Niven and Peter Sellers. She died in 2002 at the age of 71.
