Justin Timberlake has joined the upcoming musical 'Trolls.'

The 34-year-old star has signed on to voice the lead role Branch, a ''hilariously hardcore survivalist who hides his surprising true colours'', in the DreamWorks animation.

Justin, known for his roles in 'Inside Llewyn Davis' and 'The Social Network', will be joined by 'Pitch Perfect's Anna Kendrick, who will portray Princess Poppy.

The musical, which is directed by Mike Mitchell and co-directed by Walt Dohrn, will follow Branch and Princess Poppy as they embark on a thrilling adventure around the world, according to The Hollywood Reporter.

'Trolls', which is being produced by Gina Shay, is also set to star Chloë Grace Moretz and Jason Schwartzman.

Meanwhile, this isn't the first time Justin has leant his voice to a character as he also worked on the popular animation 'Shrek the Third' and 'Yogi Bear.'

'Trolls', which is being released by 20th Century Fox, is set to hit UK cinemas on October 21, 2016, and make its way across US theatres on November 4, 2016.
