Cox was nominated for an Emmy for Netflix's Orange Is the New Black where she plays Sophia Burset. Her other TV credits include Girlfriend's Guide to Divorce, Faking It, Law & Order and Bored to Death. Orange Is the New Black will return for a third season later in 2015.

Other guest stars on The Mindy Project this season include Ana Gasteyer, Julia Stiles, Ken Burns, Lee Pace, Allison Tolman, Shonda Rhimes (yes, that Shonda!), Yeardley Smith, Chrissy Teigen and Rhea Perlman.

And there's another star coming.

"We have a guest star coming up this spring that I think is the single biggest, most exciting guest star we've ever had and I can't say who it is," Kaling tells E! Online. The star is so big, Kaling couldn't even offer a hint. "No, I can't! But I'm really, really excited about it."

The Mindy Project airs Tuesdays, 9:30 p.m. on Fox.
