One of the most underrated actors of his generation, Ben Foster has just gotten engaged to someone we had no idea he was dating - Orange is the New Black star Laura Prepon.

The couple officially stepped out for the first time together at the premiere of The Girl on the Train last night in New York.

Prepon found fame early as one of the stars of That 70's Show, before landing a gig on current 'it' show OITNB.

There's obviously something in the water with that cast.

 

 

Foster is widely regarded as one of the best actors working today. He recently starred in Warcraft and Oscar contender Hell or High Water, and has a role in Da Vinci sequel, Inferno.

Prepon has The Hero due opposite Krysten Ritter and Nick Offerman.
