Although both actors are known to keep their privates live private, it seems like they broke with their own tradition and confirmed in an Instagram post - you know, the way your parents did - that they were in fact married.
The photo, which shows a beaming Prepon and Foster, was posted to Prepon's Instagram with a caption that read, "Just Married! Thank you for all the love and support. Wishing all of us the good stuff!"
Prepon was previously dating 'Crazy Ex-Girlfriend' star Scott Michael Foster (no relation to Ben), whilst Foster was dating and engaged to Robin Wright in 2014, but split in 2015. The couple, that's Prepon and Foster now, welcomed a daughter in August of last year and TMZ claimed the two married in secret back in May.
Again, they're private people so who knows - maybe just decided to let us all in on it now?
