You may have just finished binge watching "Orange Is the New Black," but season three is already taking form.

While websites continue to post reviews of the latest season, the show has started production.

Dascha Polanco, who plays Dayanara Diaz, a pregnant inmate, is now a season regular, notes the New York Daily News. And it's also good news for Samira Wiley, who portrays Poussey Washington. She will be back for season three full time.

As for Mary Steenburgen, she broke the news herself.

The Oscar-winning actress took to Twitter to share a little bit about her role.

So from that, we can gather that she is an inmate, but who knows what else the character will do. We can probably expect the actress to have a pretty important role, and we know she'll be able to handle both the funny and serious parts associated with the show.

Jodie Foster recently opened up about directing "Orange is the New Black.:

"I read the book and I said to my agent, 'Oh man, I really want to do this,'" she said, according to Out. "He was like, 'Well [the showrunner is] Jenji Kohan!' And I was like, 'Would you please pass along that I'd like to be a part of this?' Then eventually I found out a friend of mine was doing prep work for the show, and I told her, 'Please tell the writer [Piper Kerman] I love that book and I'm dying to do something.' Then that's what happened. They don't tell you what episode you're shooting so it's a wonderful exercise and meditation in letting go because you have no idea what you're doing."
