The plush Los Angeles mansion where Michael Jackson died is on sale for $23.9 million, and a major celebrity is interested in buying it, according to realtors and the TMZ celebrity website. The seven-bedroom, 13-bathroom property, described as the centrepiece of an “elegant and sophisticated French chateau estate,” includes its own movie theater, a gym and a pool, said the realtors’ website. “The estate… offers a glamorous theater for screenings in a grand style, a magnificent wine cellar and tasting room, elevator, a spacious spa with gym, and an elegant guesthouse,” as well as an “expansive pool and gardens,” it said. TMZ reported that the property went on sale on Monday, and said a “major celebrity” is set to visit it. Realtor Mauricio Umansky, head of The Agency in Beverly Hills, will only show the property to serious buyers who have pre-qualified, meaning they have the money to buy it. The singer, who was in Los Angeles rehearsing for a series of comeback London shows at the time of his death, was being treated with the drug as well as others to help him battle chronic insomnia.
