‘Orange Is the New Black’ star Laura Prepon has announced that she’s pregnant, and is expecting her first child with her fiancé Ben Foster later in 2017.

The news came a couple of days after the couple were spotted at the Sundance Film Festival, attending the Creative Coalition’s annual Spotlight Awards. The 36 year old star, an alumna of ‘That ‘70s Show’, was widely reported to have displayed a slight baby bump as she greeted fans and posed for pictures.

“Ben seemed really protective and kept very close to Laura the entire night. He was holding on to her arm as they walked in and kept by her side during the dinner,” another attendee told People on Tuesday (January 24th). “Neither of them got up much to mingle. They definitely enjoyed dinner. I noticed she finished her plate.”

Prepon and Foster, both 36, have known each other for 18 years but have only begun dating in the last two years – Foster having broken off his relationship with Robin Wright in 2014 and Prepon having split from a five-year relationship with Scott Michael Foster (no relation…) in 2013.

In October 2016, they announced their engagement to the world after Prepon showed off her engagement ring at the red carpet premiere of The Girl On the Train.

It turned out that they had kept their happy news a secret, even from some of their closest friends, including Prepon’s ‘That ‘70s Show’ co-star Ashton Kutcher.

“I get it. But private lives include friends!” Kutcher told Prepon jokingly on ‘Live With Kelly’ three months ago. “Like, I shouldn’t find out when I get off the plane!”
