Reese Witherspoon is heading to The Mindy Project!

Show creator Mindy Kaling announced the news by posting a split image of her and Witherspoon on Instagram on Tuesday.

“Our latest #themindyproject guest star is the only woman I would want to trapped in a cave with,” Kaling captioned the pic, in which Witherspoon appears to be wearing a bright red, off-the-shoulder dress. “(This is weirdly the second cave we have acted in together!) ❤️ @reesewitherspoon.”

The show premieres its final season on Hulu on Sept. 12.

After that, Kaling has a new chapter to start, as a mom, while Witherspoon will co-star in a new series about TV morning shows. Find out more about Kaling's pregnancy news below.
