Cox is set to play Tamra's cousin in the episode. According to E!, she's there to help Dr. Mindy Lahiri get her confidence back. Could this be because the hopelessly romantic doctor just found out she's—spoiler alert—pregnant? We can't wait to find out. Cox is just the latest in an all-star lineup of guest stars on the beloved Mindy Kaling sitcom. Others have included Chrissy Teigen, Ana Gasteyer, Scandal creator Shonda Rhimes, Julia Stiles, and Rhea Pearlman.
