After three long years of remodeling, Simon Cowell's $25 million mansion is finally suitable enough for the X Factor mogul to settle in!

The sprawling five-bedroom estate comes equipped with a state-of-the-art gym (so Simon can look good in those extra-tight tees!), a luxury spa with a wet steam room, a custom-made media room with a bar and plush leather seating for 20, a gallery to display Cowell's countless gold and platinum records and awards, an indoor lap pool, and separate staff quarters for a live-in butler and maid.

It's a bummer that his most recent ex-fiancee won't be joining him in the lavish sprawling estate, but luckily he bought Mezhgan Hussainy her very own $8 million abode as a consolation prize!

Welcome home, Simon!
