BBC 6Music presenter Russell Brand's joining Radio 2 to host a new late-night show on Saturdays.
The move comes after the latest RAJAR figures showed he's helped the digital station boost its audience by 40%.
Lesley Douglas, controller of both BBC stations, said: "I'm sure Russell's new show will become a 'must listen' for Saturday nights. Russell established himself as a genuine radio talent on 6 Music and has done a brilliant job there. Radio 2 gives him a fresh challenge and a new audience."
Brand proved popular with Radio 2 listeners when he deputised for Mark Radcliffe earlier this year.
His new show will go out in a weekly 9pm-11pm slot, from November 18. It will be available on podcast and Brand will also write an accompanying blog.
This Sunday's 6Music show will be his last. Another comedian who shares the same first name, Russell Howard, will take over the show.
Mr Douglas said: "Russell Howard is one of the most exciting stand-up comics around. And, yes, you do have to be called Russell to present a show in this slot!''
