Pretty Little Liars star Shay Mitchell joins Jennifer Aniston on the big screen in Garry Marshall’s upcoming romantic comedy, Mother’s Day, and she admits that even she was a little starstruck.

She plays stepmom to Jen’s kids in the film, and she said of working with her, “I’d be just sitting across from her doing my scenes, and every once in awhile I’d be like, ‘Oh my Gosh, this is so crazy!’”

Mother’s Day will hit theaters around Mother’s Day of 2016.
