'Orange is the New Black' Cast: Mary Steenburgen's Character Finally Revealed

"Orange is the New Black" is adding Mary Steenburgen to its cast for season three, and now her role has been formally announced. Steenburgen is thrilled to be joining the cast of the hit Netflix series and broke the news to fans via Twitter.

"Very excited to go to my first wardrobe fitting of OITNB! Will I be in orange or black?" Steenburgen tweeted on June 12.

Since then, fans of the series have been trying to learn all they can about her role and what it may mean for the women in prison. Now it can be revealed that Steenburgen will play Mendez, Pornstache's mom. George Mendez plays the mustached former corrections officer at Litchfield Penitentiary. Officer Pornstache is one of the most despised characters on the show.

He smuggled drugs into the prison with Red's help and continually provides drugs to the inmates for sexual favors. The drugs he smuggled led to Tricia Miller's addiction, overdose, and death; he, however, managed to make it look like a suicide in order to avoid punishment.

The inmates, however, hatch a plan to get Pornstache out of the prison system for good. Once Daya Diaz realizes she is pregnant by another man, the inmates work together to frame Pornstache for the pregnancy. He was terminated from his position and incarcerated for raping a prisoner.

It's unclear how Steenburgen's motherly role will add to the drama of the series, but it will certainly be interesting to see whether her son learned all of his tricks from her or whether he is the exact opposite. Steenburgen has often played the mother of difficult children: she took care of Will Ferrell's extremely dependent and unstable character, Brennan, in "Step Brothers" and managed to come away unscathed.

The second season of "Orange is the New Black" was just released on Netflix, and now viewers cannot wait until the third is finally released.
