Paul Ross will go head-to-head with brother Jonathan, after signing a deal to present on BBC Southern Counties Radio.
The new show, which will broadcast between 9am and midday, is part of a new weekend schedule for the station.
The new schedules, which begin on Saturday 5th April, also include a new Saturday lunchtime show hosted by CBeebies presenter Sid Sloane.
Talking about his new show, Ross said: "We'll be doing features like Weekly Weird News as well as raiding my celebrity contacts book. Plus we also want to give people an idea of what to do with their weekends, and get them involved in the show."
"And the great thing is that for the last two hours of the show I'll be up against my brother. I am not nervous, but I think he's a bit worried!"
Managing Editor for BBC Southern Counties Radio Nicci Holliday said: "The minute we met with Paul and Sid, we knew they were perfect for the station, great big personalities, brilliant storytellers with warmth and authenticity. Both are rooted in the Southern Counties and know the patch almost better than we do!"
