Gisele Bundchen's new $20 million home has a moat.

The supermodel and her New England Patriots quarterback husband Tom Brady bought the palatial mansion in Brentwood, Los Angeles over three years ago and have refurbished it to include a a resort-style swimming pool in the back yard, a castle-like custom play area and a moat with a bridge.

The home also included eight bedrooms, a wine cellar, gym and a six-car garage

Although Gisele, 32 and Tom, 35 - who have children Benjamin, three and Vivian, seven weeks, together along with Tom's son John, five, from a previous relationship - have previously come under fire for having such a large home, but Gisele insists they plan to be environmentally friendly.

She explained: ''We are excited to be using solar power as the main source of electricity in our home/ And we are planting our own herbs, fruits and vegetables, which will be my favorite part of the house.''

Other famous faces who live in Brentwood include Reese Witherspoon and her husband Jim Toth, talk show host Chelsea Handler and Arnold Schwarzenegger.
