Apparently the skyline around the Ravens Stadium in Baltimore is running short on douchey billboard space. So Kevin Plank, founder of Under Armour finds a way to spend 8 million dollars in Georgetown.

Kevin Plank, the 40-year-old billionaire founder of Under Armour, has reportedly just closed on one of Georgetown’s most glamorous mansions, which comes complete with eight bedrooms and a ballroom. Plank paid in the vicinity of $8 million for the sprawling house at 1405 34th Street, Northwest, according to a well-connected source. An even less connected source could tell you, you'd have to sell a lot of men's spandex underwear to break 8 million.

The home was put on the market with an asking price of $8.9 million by Deborah Winsor, who recently bought and moved into the former Dumbarton Street home of disgraced World Bank bossDominique Strauss-Kahn. Winsor’s husband, Curt Winsor, died last year. Winsor paid $3.3 million for the DSK house.

Plank’s new home, his second in Georgetown, comes with a glamorous provenance. It was the home of an American aristocrat, former ambassador David K.E. Bruce and his wife,Evangeline Bruce. They entertained often and put the ballroom in particular to good use. In its time it was the gathering place of Georgetown society. David Bruce died in 1977. Evangeline lived there until her death in 1995. Between the Bruces and the Winsors, it was home to biographer David Michaelis—who has written books about cartoonist Charles M. Schultz and artist N.C. Wyeth—and his then-wife, Clara Bingham.

Plank’s wildly successful sports apparel business was founded in Baltimore. He attended Georgetown Preparatory School in Bethesda, St. John’s College High School in DC, and the University of Maryland.
