Big Little Lies star (and Emmy nominee) Reese Witherspoon is returning to the small screen for a guest role on Hulu’s The Mindy Project, creator and star Mindy Kaling revealed on her Instagram Tuesday.
In the photo Kaling posted, Witherspoon’s decked out in what looks like a red, off-the-shoulder dress, while Kaling is gripping a phone and wearing a puffy vest—oh, and they’re both in a cave.
“Our latest #themindyproject guest star is the only woman i would want to trapped in a cave with,” Kaling captioned the photo. “(This is weirdly the second cave we have acted in together!)”

That first cave was likely on the set of Ava DuVernay’s upcoming A Wrinkle in Time adaptation, in which Kaling and Witherspoon costar along with Oprah Winfrey.
