A new tell-all book about Elizabeth Taylor’s life claims she had a threesome withJohn F Kennedy and an affair with Ronald Reagan.

The book “Elizabeth Taylor: There is Nothing Like a Dame”, written by Danforth Prince and Darwin Potter, makes shocking allegations about the Hollywood star’s love life. The book’s authors say they spent years researching the legend’s life. She died in 2011.

They claim that 36-year-old star Ronald Reagan invited Taylor, who was only a teenager at the time, to dinner at his home. She seduced him.

The Daily Express reports that a close friend of Taylor said the actress had told her the story about the future President of the United States before.

The books states, “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.”

This tell all book also claims that in 1948 a skinny dip in John F Kennedy’s swimming pool turned into a steamy threesome with the future President and actor Robert Stack. Both men were married at the time.

Porter told the New York Daily newspaper, “JFKwas known for swimming in the nude.

“This one got a little wild.”

The book also details sexual encounters with stars such as Peter Lawford, Errol Flynn, Tony
Curtis, and Paul Newman.

Porter said, “Everyone who I came into contact with, from Mary Astor to Tallulah Bankhead, had a tale to relate about Elizabeth — either good or bad, often a combination of both.”

The unauthorized book says it will deliver “all the gossip unfit to print from the glory days of Hollywood.”

Taylor died aged 79. She had been married eight times. The upcoming Lifetime biopic “Liz & Dick” will tell the story of Taylor’s two marriages to actor Richard Burton. The Irish American actress Lindsay Lohan will play Taylor.
