Ben Foster and Laura Prepon certainly turned heads at the NYC premiere of The Girl on the Train [1] on Tuesday night. Not only did they make their red carpet debut as a couple, but they also confirmed their engagement [2] when the actress flaunted some new bling on her ring finger [3]. While Ben looked dapper in a gray suit, Laura paired her gorgeous sparkler with a fitted blue dress. The pair was first linked back in July when they were spotted out and about together in the Big Apple, but the Orange Is the New Black [4] star has actually known her fiancé since she was 18. They're mutual friends with her That '70s Show [5] costar, Danny Masterson. Ben was previously engaged to actress Robin Wright [6], whom he had an on-again, off-again romance with from 2012 until 2015. Congrats to the happy couple!
