Simon and Britney Do Not Really Own X Factor Mansions

In case you missed last night's episode, groups of contestants were invited to perform at four different homes around the country -- each allegedly belonging to one of the show's four judges.

But it was ALL A LIE -- "Simon's" Miami pad actually belongs to A-Rod. The baseball star listed the home in August for $38,000,000, but it's still on the market. Simon's real house is in Beverly Hills.
