Very excited to go to my first wardrobe fitting of OITNB! Will I be in orange or black?:) — Mary Steenburgen (@MarySteenburgen) June 12, 2014

And with that, we’ve got another new member of the already-stacked Orange Is the New Black cast for Season 3. Mary Steenburgen is a widely accomplished actress who has been in everything from Justified to Step Brothers, so there’s really no predicting what role she’ll be playing.

Her purposely coy tweet leaves her role entirely up in the air, but with the new season already in production we’re sure to find out soon.
