The 'Orange Is the New Black' star has announced she is expecting another baby with her actor spouse Ben Foster.

She wrote on Instagram: "We are so excited to announce that our family is growing. Life is beautiful! #knockedup (sic)"

Laura and Ben - who already have Ella, two, together - married back in June 2018, after previously confessing she wanted a small wedding.

Taking to Instagram at the time, she wrote: "Just Married! Thank you for all the love and support. Wishing all of us the good stuff! (sic)"

And confessing that she wants a "really small wedding", she added: "We want a really small wedding but we have a lot of people that we love and care about. It's weird, [but] apparently doing the list for your wedding is a whole thing that could cause some issues. [The 'Orange is the New Black'] cast alone is like 50 people. He's going off to do two movies. I just wrapped last week. It's just, you know, scheduling. It's a lot."

Laura had previously opened up about motherhood and the challenges of balancing a career and being a mom.

She said: "Ben and I are really great about if I'm at work, he's [at home], and if he's at work, I'm [at home]. But] I do feel guilty, and I just know that she'd be proud if she knew. I've talked to a bunch of women [asking], 'How do you do this?' And they're just like, 'There's really no solution. You just do it.'"
