Britney Spears’ career has always been up and down, but despite all her problems, thankfully she’s also made some very good decisions in her life like where she invested her money. The pop star bought a giant 13,264-square foot mansion in California worth $9 million. The Italian villa is filled with 5 bedrooms, 8 baths, a library, a granite kitchen, and even a wine cellar that can hold up to 3,500 bottles.
