It's the future Mr. and Mrs. Foster! Robin Wright and brand-new fiancé Ben Foster were arm-in-arm on the red carpet for Sunday's 2014 Golden Globe Awards in Beverly Hills -- their second appearance together since yesterday's surprise news of their engagement. The House of Cards actress, 47, looked elegant as ever in a gold-beaded halter gown by Reem Acra, with her hubby-to-be, 33, in an all-black ensemble and forgoing a tie.

Wright first debuted her engagement ring at a Diane von Furstenberg bash in L.A. on Friday. It will be the first marriage for Foster but the third for Wright, who divorced Sean Penn back in 2010, and Dane Witherspoon in 1988.

Penn, 53, meanwhile, is slowly going public with his latest love: Charlize Theron. Wright and the Oscar-winning actor share daughter Dylan, 22, and son Hopper, 20.

"Ben is a sweet guy and you don't even notice the age difference. He's a lot more mild-mannered than Sean [Penn]," a source close to Wright told Us. "And Robin's kids Dylan and Hopper like him and like seeing their mom happy."
