This place is so massive, we don't even know where to begin!

Britney Spears is celebrating her comeback year, and her upcoming album Femme Fatale, with a brand new $20 million mansion located in the very private Hidden Hills community of LA.

The Hold It Against Me singer's new spread is mock Tudor-style and provides over 20,000 square feet, and three acres, of awesomeness. The pad has 13 bathrooms, 10 bedrooms, a huge ballroom (so Brit can host dance parties!) a game room complete with air hockey table, pin ball machines and arcade games, a tennis court, swimming pool, multiple hot tubs, caves and waterfalls. Wow.

Brit's sons Sean Preston and Jayden James will never want to leave! We can just imagine the house-party potential this place has got. Spears better not leave her boys home alone when they reach their teens.

But here's the best part: the village-like area the mansion is located in comes complete with its own Starbucks. That was probably the deal-breaker for Spears. How could she pass up a property which includes her favorite coffee joint?
