Are Paul Mescal and India Mullen a couple? That’s the question that’s on many fans’ minds after the 24-year-old hunk shared an eye-catching photo with his Normal People co-star on Instagram on Aug. 21. In the cute snapshot, Paul is sitting on the floor of what looks like his apartment as he rests his elbows on his knees and gives a grin to the camera, and the 23-year-old blonde beauty is sitting near him in a chair as she leans in and has one arm up and close to his shoulder.
