Twins Joel and Benji Madden are working on a new album together under The Madden Brothers, while their band Good Charlotte takes a break for a year.
Joel is currently appearing as a coach on Channel Nine's The Voice, while his brother Benji is a mentor.
He told News Limited that when they're not in Australia, he and Benji have been working in Los Angeles with the likes of Pharrell Williams on a record, which is due for release this year.
Joel said it's been great having Benji work on The Voice with him in Australia, "but also writing and producing music together and also working on a Madden Brothers record while Good Charlotte take some time off".
The pair are reportedly also writing music with Aussies like Jimmy Barnes, Shannon Noll and Reece Mastin.
