Things between Joe Jonas and Sophie Turner are “better than it’s ever been” since the pair split. The Jonas Brothers member, 35, and the Game of Thrones star, 29, “have gotten into a co-parenting rhythm that really works and they’ve figured out how to communicate,” a source tells PEOPLE exclusively.

The “Do Revenge” actor opened up about her unique schooling on the subject on a recent episode of the hit U.K. “Dish” podcast, released on Wednesday. Co-host Nick Grimshaw asked Turner about her time on the HBO series “Game of Thrones,” and the 29-year-old revealed just how much she learned from the show.
