Congrats! Homeland actor Rupert Friend is engaged to his girlfriend Aimee Mullins, multiple sources confirm to Us Weekly.

Mullins, a double-amputee who competed as a collegiate and Paralympic sprinter before becoming a model, let the news slip of their engagement on Tuesday, Dec. 2, at the L'Oréal Paris Women of Worth awards.

The L'Oreal spokeswoman was presenting an honoree when she was given a congratulatory shout-out on the engagement, a source tells Us, adding that the blonde was also calling Friend, who portrays Peter Quinn on the hit Showtime series, her "fiancé" on the red carpet.

Before splitting in 2011, Friend was previously linked to his Pride & Prejudice costar Keira Knightley for five years.
