The 10,000-square-foot Mediterranean-style home, which was originally listed two years ago, is "full of style, creative decor and ultimate elegance," according to the listing.
The six-bedroom, nine-bathroom mansion has a grand foyer with a sweeping staircase, a "fanciful" children's room, game room and gift-wrapping area. The house also includes a gym, movie room, beauty salon and, of course, a recording studio.
Outdoor amenities on the property include a pagoda, pool with water-slide and grotto spa.
