Liz Taylor's steamy affairs with Reagan and Kennedy exposed

Elizabeth Taylor allegedly slept with Ronald Reagan when she was a teenager and enjoyed a threesome with President John F. Kennedy and actor Robert Stack.

Authors Danforth Prince and Darwin Potter have spent years tracking down the scandalous details of the legendary actress' romances and affairs and they have laid her private life bare in an explosive new biography Elizabeth Taylor: There is Nothing Like a Dame.

In the book which promises "all the gossip unfit to print from the glory days of Hollywood", Prince and Porter claim Reagan was 36 when he invited a teenage Taylor to dine with him at his Hollywood Hills home, where she seduced him, the Daily Express reported.

She is believed to have told a close pal, "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 further goes on to claim that a nude dip in the politician's pool turned into a threesome with Taylor and Stack.

The authors claim the actress went on to have sexual encounters with stars including Peter Lawford, Errol Flynn, Tony Curtis, Paul Newman and Frank Sinatra.
