Actress Kerry Washington has secretly exchanged vows with American football star Nnamdi Asomugha.

It was revealed the Django Unchained beauty, 36, was dating the San Francisco 49ers cornerback, 31, on Wednesday afternoon (03Jun13), and just hours later sources tell Eonline.com the couple is man and wife.

Reports suggest Washington started dating the former Oakland Raiders and Philadelphia Eagles star last summer (12), and they walked down the aisle at a low-key ceremony in Blaine County, Idaho on 24 June (13).

It is Washington's first marriage - she was previously engaged to actor David Moscow, but they called off the relationship in 2007.

The newlyweds are believed to have bonded over their shared love of philanthropy as both are involved in former U.S. President Bill Clinton's non-profit organisation for global change, the William J. Clinton Foundation.
