Gives a whole new meaning to house music -- 29-year-old badass Calvin Harris just dropped $7 million on one of the most insane Hollywood Hills mansions we've ever seen. According to legal docs, Calvin -- real name Adam Wiles -- purchased the 4,000-square-foot pad last month. Like a true baller CH dropped MILLIONS upfront, only taking out a $4.9 million mortgage. Now to the house ... or should we say really-awesome-crazy-amazing-mansion. It's got 4 bedrooms, 7 baths, top-of-the-line everything, infinity edge pool, chef's kitchen, home theater, built-in fire pit lounge, floor-to-ceiling windows, plus panoramic L.A. views.
