An “Orange is the New Black” cast member is expecting her first child!

Laura Prepon and her fiancé, Ben Foster, attended the Creative Coalition’s annual Spotlight Awards at the Kia Supper Suite at the Sundance Film Festival on Sunday night. While there, a source told People that Foster seemed to be sticking to Prepon all night, and it was later on revealed that it was because she’s pregnant.

“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. Neither of them got up much to mingle. They definitely enjoyed dinner. I noticed she finished her plate,” the source said.

Prepon and Foster have kept their relationship low-key since getting together. In October 2016, she appeared on “Live With Kelly” with her good friend, Ashton Kutcher. During the interview, which took place just three days after Prepon got engaged, Kutcher joked that he only found out about it when he got off the plane. “I get it. But private lives include friends! Like, I shouldn’t find out when I get off the plane!” he said.

Meanwhile, Prepon plays the role of a lesbian named Alex Vause in the hit original Netflix TV series “Orange is the New Black.” The series is set to stream its latest season online starting this June.

Ahead of its release, Netflix already confirmed the renewal of “Orange is the New Black” for Seasons 6 and 7. Series creator Jenji Kohan previously expressed her gratitude over the renewal, saying that she’s excited to do more interesting things on the show. “And kudos and gratitude to the stellar cast and crew and writers and producers and editors and musicians and mixers and shleppers…. With whom I have pride and honor of crafting this show. Three more years! Three more years!” she said.
