'Cho Chang' aka Katie Leung will be seen in Bridgerton season 4.

Luke Thompson and Yerin Ha will star as Benedict Bridgerton and Sophie Baek in the new season. The show will also introduce new characters, including Katie, known for her role in the Harry Potter films.

Katie, 37, will play Lady Araminta Gun, a character described as "twice married and twice widowed." Her two daughters, Rosamund Li (played by Michelle Mao) and Posy Li (played by Isabella Wei), are making their debut on the marriage market this season. Lady Araminta is "feeling the pressure to get at least one of [her girls] married off," with Rosamund setting her sights on Benedict Bridgerton.

Season 4 will focus on Benedict Bridgerton's love story. Benedict is described as "loath to settle down" despite his brothers Anthony and Colin being "both happily married." Most of the cast from the previous season will return, but Simone Ashley, who plays Viscountess Kate Bridgerton, is not confirmed for the upcoming season.

A source told PEOPLE that Simone, 29, "adores her Bridgerton family and cast and would be happy to come back at any point if storyline allows."

Seasons 1-3 of Bridgerton and its spin-off, Queen Charlotte: A Bridgerton Story, are available for streaming on Netflix. The fourth season of Bridgerton is adapted from An Offer from a Gentleman, the third of Julia Quinn's novels. All eight Harry Potter movies can be streamed on HBO Max.
