Simon Cowell And Former Fiancee Mezghan Hussainy Heat Things Up On His Yacht

Carmen Electra who?

On Friday Simon Cowell and his former fiancee Mezghan Hussainy were spotted on his $167 million yacht in St. Barth, and even though he claims they're just friends these days, we have to wonder why she's wearing a skimpy bikini and practically climbing on top of him!

Simon and Mezhgan got engaged in 2010, but called things off early last year, and at the time the X Factor mogul told The Sun that he made a mistake asking her to marry him. "We came to the conclusion that I’m a hopeless boyfriend," he said. Ouch! But he did reportedly gift her with a multi-million dollar mansion in Beverly Hills, so she didn't get a totally bad deal...

So what about Carmen? Ryan Seacrest chatted with Cowell just two weeks ago and asked about their romance, to which the mega-wealthy producer replied, "She's not my girlfriend. We're people who date. She's adorable, isn't she?"
