Mindy Kaling visits 'It's Always Sunny' set ahead of Season 13

June 20 (UPI) -- Mindy Kaling stopped by the set of It's Always Sunny in Philadelphia this week.

The 38-year-old actress posted a photo Tuesday of herself reading the script for the FXX series Season 13.

The picture shows Kaling wearing jeans, sneakers and a t-shirt as she goes over a script. The back of the script reads "It's Always Sunny in Philadelphia 13" and is dated June 18.

"It's always sunny when you're visiting your friends on @alwayssunnyfxx #Season13," Kaling captioned the post.

Rob McElhenney, who plays Mac McDonald on It's Always Sunny, had shared a since-deleted photo with Kaling and his co-stars Charlie Day, Kaitlin Olson and Danny DeVito earlier this week.

"We're proud to announce the new member of the gang. We found her through a grueling audition process but we think this fresh-faced kid deserves a shot. This lady has a bright future. #sunny #season13," the actor wrote.

McElhenney guest starred as Lou Tookers on Kaling's series The Mindy Project, which ended in November after a six-season run. Kaling plays Priya Patel on the NBC series Champions, which she co-created with Charlie Grandy.
