Hong Kong-based billionaire Cecil Chao Sze-tsung has offered a $65 million “marriage bounty” to the man who can sweep his lesbian daughter off her feet.

The 76-year-old property billionaire made the offer after reports that his daughter, Gigi Chao, 33, entered a domestic partnership with her long-term girlfriend, Sean Eav, in France.

He denied reports of his daughter's nuptials and insisted she is still single.

“I don't mind whether he is rich or poor – the important thing is that he is generous and kind hearted,” he told the South China Morning Post.

“Gigi is a very good woman with both talents and looks. She is devoted to her parents, is generous and does volunteer work,” he said.

Mr. Chao, who has never been married himself, has three children with three mothers and claims to have bedded more than 10,000 women.

In addition to the “marriage bounty,” he has offered capital to his potential son-in-law to start his own business.
