Xuxa, who has previously dated late racing driver Ayrton Senna and soccer legend Pele, was invited to see the late King of Pop several times and had dinner with him before one of his entourage suggested that she should marry Jackson, reported Sun Online.
"The entourage of Michael Jackson wanted him to marry, have children. They were looking for someone. I was working in Spain, they invited me to see his show several times. Later they called me to invite me to Neverland. He knew everything about me, he read everything about me. I had dinner with him.
"And later came a proposal from his impresario asking me whether I would consider living with him because he wanted to have children, marry. They thought marriage with a person concerned about children in Latin America would be a good thing," said Xuxa, whose real name is Maria da Graca Meneghel.
Although Xuxa - who is Brazil's richest woman with an estimated fortune of USD 1 billion - was a big fan of Michael, who died of acute Propofol intoxication in June 2009, she turned down the proposal.
"For me Michael Jackson was an idol, but from idol to something else there is a difference. My answer, obviously, was no."
Jackson went on to marry twice. He first tied the knot with Elvis Presley's daughter Lisa Marie and was with her for just under two years until 1996. He then married nurse Debbie Rowe but divorced her in 1999.
