v7678, BEVERLY HILLS, CALIFORNIA - March 7, 2010. "American Idol" judge Simon Cowell owns this $20 million mega-mansion located in the heart of Beverly Hills. The 50-year-old music mogul paid $8 million (£5m) for the lot in September of 2004 and had the original home demolished to make way for this dream home which he had constructed from the ground up. The recently completed 11,550 square foot mansion has 5 bedrooms, 6 bathrooms, a state-of-the-art gym, luxury spa complete with wet steam room, lap pool, guest house, high-tech media theatre and a solarium.
