'Orange Is the New Black' Star Laura Prepon Expecting First Child

Congrats are in order for new parents-to-be Laura Prepon and fiancé Ben Foster!

The "Orange Is the New Black” actress has been taking in Sundance Film Festival with the “Six Feet Under” actor. Last night, the 36-year-old received a Spotlight Award at the Creative Coalition's annual awards.

A source told People, “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.”

An onlooker added, “Neither of them got up much to mingle. They definitely enjoyed dinner. I noticed she finished her plate.”

The two have known each other for 18 years, and got engaged in October after keeping their relationship very low-profile.

After learning of the engagement, Prepon's former “That '70s Show” co-star Danny Masterson took to Instagram to share a throwback photo and his excitement, writing, “This little baby just got engaged. Over/under on me crying at the wedding…”
