We're not sure what's hotter ... Gisele Bundchen and Tom Brady as a couple OR their new $20 million mega-mansion in Brentwood?

Looks like the sprawling estate will be powered by the sun. Check out all of those solar panels!

The 22,000 square-foot home features eight bedrooms, a wine cellar, personal gym, two wings connected by a bridge, a state-of-the art nursery, lagoon-style pool and a parking facility for six cars.

Gisele and Tom have been working on this home for the past eighteen months. The power couple bought the 3.75-acre property back in 2008 ... before 18-month-old son Benjamin was born.

After seeing this gorgeous property, seems well worth the wait!
