The 73-year-old billionaire said a week per month for each girlfriend was “pretty much the general rule”, though he has kept mum on the identities on all but one of his quartet.

Turner got busy spreading his seed after divorcing from his third wife, Oscar-winning actress, Jane Fonda in 2001, following 10 years of marriage.

He still speaks to Fonda about once a month and, according to one friend, is “still in love with her”.

The media mogul and philanthropist, who owns 28 homes including four ranches, told The Hollywood Reporter: “Jane said ‘I want two homes, a winter home and a summer home. I don’t want 10.’ And she couldn’t take the travel.

“Really, it’s much harder for a woman than a man.

“What am I supposed to do, sit down and cry? I did for six months. And after that, you gotta go on.” In a wide ranging interview with the magazine Turner also admitted he had considered suicide. He said: “I’ve thought about it and decided against it – in the past, not recently.”

One of Turner’s latest squeezes is novelist Elizabeth Dewberry. Until five years ago, Miss Dewberry was married to the Pulitzer Prize-winning author Robert Olen Butler.

An email from Butler to his friends, which was leaked to the media, read: “She will no be Ted’s only girlfriend. Ted is permanently and avowedly non-monogamous. But though he has several girlfriends, it is a very small number, and h e does not take them up lightly.”

Asked if his other three lady-friends were happy to share him, Turner replied: “Sort of.”

Turner commented on the scandal engulfing Rupert Murdoch, saying his long time business rival should “resign or step down” if New Corp was found guilty of breaching the law.

“When I was a publisher of CNN, I took responsibility for the actions of the network,” Turner said.

“Turner has an estimated wealth of $2 billion, and is America’s second largest private landowner.

He has recently poured his money into environmental causes, and owns more than 50,000 bison.
