It has been claimed that Elizabeth Taylor not only did have a string of romances with fellow screen stars – but also with Presidents Ronald Reagan and John F. Kennedy.

The former liaison allegedly occurred when Elizabeth Taylor was a teenager, with the latter encounter reportedly taking place as a threesome with actor Robert Stack, according to an explosive new biography.

Elizabeth Taylor: There is Nothing Like a Dame – penned by authors Danforth Prince and Darwin Potter – is an unauthorized biography that explores the colorful love live of the late National Velvet star.

According to the book, Elizabeth Taylor confessed to a friend after she was seduced at Ronald Reagan’s Hollywood Hills home, saying: “Reagan was treating me like a grown woman, and that thrilled me.

“We sat on his sofa and I could tell he wanted to get it on but he seemed reluctant to make the first move. I became the aggressor.

“After a heavy make-out session on the sofa, we went into the bedroom.”

The book claims Ronald Regan [born in 1911] was 36 at the time of the alleged encounter, which means it would have been 1947.

That would put Elizabeth Taylor, born in 1932, at just 15-years-old.

The authors claim it was a nude dip in JFK’s pool that would turn into a threesome between the actress, the politician and actor Robert Stack.

Danforth Prince and Darwin Porter allege Elizabeth Taylor also counted Peter Lawford, Errol Flynn, Tony Curtis, Paul Newman and Frank Sinatra as lovers – her romance with Ol’ Blue Eyes becoming one of the more serious.
