Britney has had quite the week, and we love it all! She showed up looking fabulous on Letterman and then shockingly filed for divorce from K-Fed. Now Brit has apparently put her Malibu mansion on the market for $13.5 million. She bought the house when Kevin was unemployed for $6.9 million in 2004. The new lucky owner will not only get to live in the spot Britney once called home, but will get to enjoy an outdoor kitchen, spa, gym, tennis courts, a $150,000 nursery and a recording studio.
