Stephen Moyer and Samantha Barks will be taking to the Los Angeles stage for a short run of the musical Chicago.
True Blood star Stephen and Les Miserables actress Samantha will join the musical at the Hollywood Bowl for three performances in July, said the LA Times.
Stephen will take the role of lawyer Billy Flynn, while former I'd Do Anything contestant Samantha will star as murderer Velma Kelly.
The production is being directed by Brooke Shields, an ex-Roxie Hart on Broadway.
Casting for Roxie has not yet been announced, but the supporting cast also includes Drew Carey and Xena: Warrior Princess's Lucy Lawless.
Samantha tweeted: "Very excited to announce that I will be playing Velma Kelly in Chicago at this year's Hollywood Bowl!! I'm so excited!"
The long-running musical follows a group of women on death row and the lawyer defending them. It was adapted into a film in 2002 starring Catherine Zeta-Jones, Renee Zellweger and Richard Gere.
The LA production will run from July 26 to 28.
