Ivana Trump in 'toyboy' TV show

Trump is currently dating younger man Rossano Rubicondi

Ivana Trump is set to follow her billionaire ex-husband Donald into reality TV, in a show which sees an older woman find a younger partner.

Eight young bachelors will vie for the affections of an older woman in the show, with the working title Ivana Man.

Following Mr Trump's success with the series The Apprentice, Mrs Trump will host the two-hour TV special on Fox.

Czech-born former model Trump, 55, will play matchmaker on the programme, to be broadcast in the autumn.

Trump will select the eight bachelor contestants. The group will subsequently be whittled down to two finalists, before a winner is chosen, with Trump's help.

The "older" woman picked for the show will probably be in her 40s, according to the Fox TV network.

"For years, rich, older men have traded in their wives for pretty young women with bigger 'attributes'," Fox reality TV executive Mike Darnell said in a statement.

But now "thanks to women like Ivana Trump, Demi Moore and Cher, the social norms are changing, and mature women are finding that true love can happen with younger men," he added.

Babysitter

Mrs Trump says she, too, prefers the company of younger men: "I cannot be with an older man. They're too set in their ways."

"I prefer to be a babysitter than a nursemaid," Mrs Trump told British newspaper the Daily Mail.

Her current boyfriend, Rossano Rubicondi, is more than 20 years her junior.

The show's executive producer Scott Stone told trade paper Daily Variety that when he first approached Mrs Trump about doing the show, her reaction was: "Darling, that's me. That's perfect."

Donald and Ivana Trump married in 1977 and divorced in 1992.

He married younger model Marla Maples the following year. They divorced in 1999.

He has since become engaged to model Melania Knauss.

A second series of The Apprentice is set to begin showing in the US next week.
