Sophie Turner's latest project will see her as an animated version of Prince William and Duchess Kate's 5-year-old daughter, Princess Charlotte! As Entertainment Tonight shares, Turner— who's known for playing "Queen Sansa Stark" in the HBO fantasy series Game of Thrones— is lending her voice to the young royal in HBO Max's The Prince!

Turner's "Princess Charlotte" sasses brother in clip

Turner's casting as "Princess Charlotte" in The Prince was revealed on Saturday when the show's creator, Gary Janetti, shared a new clip on social media! "Meet Charlotte - Sophie Turner @sophiet The Prince coming to @hbomax," Janetti wrote on Instagram. In the sneak preview, William and Kate's three kids are seen dressing up for Halloween.

Even though "George" says the trio will be going as the Three Little Pigs, his siblings have other plans! "Charlotte" dresses as "Dorothy" from The Wizard of Oz, while "Louis" is a vampire. "Come on, it's a group costume! It doesn't work unless we all do it," says a frustrated "George". "Maybe say you're Ariana Grande's pet pig?" replies "Charlotte" in response.

Turner joins celeb voice cast for HBO royal parody

Turner joining The Prince as "Princess Charlotte" means the actress is the latest name to be added to the royal parody's star-studded cast list! As Entertainment Tonight mentions, Janetti voices "Prince George," while Alan Cumming is George's butler, "Owen," and Frances de la Tour gives her voice to "Queen Elizabeth II"!

"Prince William" and "Duchess Kate" will be played by Iwan Rheon and Lucy Punch, respectively. Orlando Bloom was tapped to voice "Prince Harry" alongside Condola Rashad's "Duchess Meghan," and he recently opened up about playing the royal!

While the show doesn't have a release date yet, it was announced back in January that the HBO Max parody "follows an animated Prince George spilling all that British Royal Tea." See the new clip from The Prince featuring Sophie Turner as "Princess Charlotte" here!
