Orange Is The New Black star Laura Prepon is pregnant with her first child

Orange Is The New Black star Laura Prepon is expecting her first child with fiancée Ben Foster.

The couple are known for being notoriously private and have not spoken out about the happy news themselves yet, with a source confirming the pregnancy to People magazine.

Laura, who is best known for her role as Alex Vause in the Netflix original comedy-drama series Orange Is the New Black, became engaged to Ben back in October.

Now the loved-up pair are expecting a child together, and the sweet news comes just a day after the couple stepped out together at the Creative Coalition's annual Spotlight Awards on the weekend.

An on-looker spoke to People magazine giving some insight into the couple, who by the sounds of things seem very in love, '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.'

Laura and Ben stayed very private at the time of their engagement too, choosing not to speak about it or their relationship in the media but to let her sparkler do the talking.

It was at the premiere of The Girl on the Train in New York when the couple arrived on the red carpet together, with Laura sporting a beautiful diamond engagement ring. Sending the media into a frenzy, rumours started that they were engaged which lead to a confirmation from a source to E! News.

The husband and wife to be have a long history behind them, having known each other for 18 years.

When speaking to Cosmopolitan magazine back in 2014 Laura opened up about her love life saying, 'When I'm working, it's next to impossible.

'I like to think I'll just be walking down the street one day and stop and meet someone, like, "Oh, my god, you're awesome," and then we start dating. But, no.'

We're so glad Laura has finally found that 'awesome' someone, congratulations to the happy couple!
