The pop diva snapped up a Los Angeles-area 11,000-square foot manse in December that has seven bedrooms, nine baths, media rooms, a sun deck, a pool, a 6,000-square-foot garden, and an outdoor barbecue area. The new purchase came on the heels of a short sale tied to a Beverly Hills home that she had scooped up in 2009 only to have it flood and suffer extensive flood damage.
