Donna's had a baby! And we didn't even know these two were a couple.

'Orange is the New Black' star and 'That 70's Show' alum Laura Prepon welcomed her first child with fiancé Ben Foster earlier this month, according to Us Weekly.

Prepon and Foster, who only began dating last year despite being friends since their teens, announced their engagement last October and welcomed a baby girl this month whose name is yet to be revealed.

Prepon revealed her pregnancy at Sundance at the start of the year, and spoke about it in June while eight months pregnant and announced that a girl was on the way, saying: "It’s kind of weird, ‘cause it sneaks up on you where you’re like, ‘I can’t believe it’s been eight months already. But then you’re like, ‘Oh my God, she needs to like come out already."

We've come a long way since Eric's basement...
