Zoe Ball is to take over from Claudia Winkleman as the host of BBC2's Strictly Come Dancing spin-off.
The former Strictly contestant and mother-of-two will take over fronting It Takes Two when the new series begins in the autumn.
Claudia, 39, had hosted the show - with behind the scenes interviews and gossip - since it began in 2004.
She is due to give birth to her third child weeks before the new series starts.
Zoe, 40, said: "I am quite literally beyond elation. There has been quite a hullabaloo at home with the news.
"I'm giddy with glee and I may even have slipped momentarily into a celebratory Cha Cha Cha, although technically not a very good one.
"Having been a contestant myself and having hosted the Strictly Come Dancing Tour, it would be fair to say I'm obsessed with the whole dance phenomenon.
"I love everything Strictly, from watching the partnerships blossom and bloom to the tricky footwork, the frocks and the shock exits, and of course the judges."
TV and radio presenter Zoe - who has two children with DJ husband Norman Cook, aka Fatboy Slim - competed in the show in 2005 with professional partner Ian Waite, coming third behind athlete Colin Jackson and cricketer Darren Gough.
