Maria Shriver Extreme Home Makeover

As we first reported, Maria has purchased a home in Brentwood, CA near the family home which Arnold will get in the divorce.

Maria's new home -- which she bought for around $10 mil -- is 11,000 square feet, and every inch is being redone.

It will have 8 bedrooms, 7 bathrooms, a 3-car garage, a gym, theater and wine room. We're told the house will be completed in 3 months -- good luck with that.
