Dr. Dre about to buy New England Patriots QB Tom Brady's mansion.

Tom and his supermodel wife Gisele listed the 18,700 sq. ft. Brentwood estate for $50 million and Dre fell in love.

The deal is not yet finalized but it's close. Dre is also interested in buying The L.A. Clippers since the NBA is trying to push out Donald Sterling.

How is Dr. Dre affording all this? Well when you're worth over $500 million dollars, money ain't a thing.
