Boyzone's Ronan Keating is to present a Sunday show on London radio station Magic 105.4, it has been announced.
The 32-year-old singer - who has been a guest presenter for the easy listening station in the past - will broadcast his first two-hour show on Sunday.
The Irish performer said he was "really excited about getting behind the mic and choosing my favourite tunes".
It has also been announced Gaby Roslin will co-host BBC London's breakfast show with Paul Ross from next week.
The move sees Roslin, 45, occupy the same time slot as her former Big Breakfast co-host Chris Evans, who takes over the Radio 2 breakfast show on the same day.
"I've always said I would never do a breakfast show again," said Roslin, who once presented a show on Five with Evans' predecessor Sir Terry Wogan.
"But the lure was just too strong and I couldn't resist the opportunity of working on my favourite station."
Keating, 32, is no less enthusiastic about appearing on Magic, saying he wanted to "show everyone I am not only a singer, but a broadcaster as well".
Programming director Pete Simmons said he was "incredibly popular with our listeners, as a personality and as a performer and songwriter".
