Fearne Cotton is to take over from Jo Whiley on the weekday mid-morning show in a major shake-up of Radio 1's schedule. Both Jo Whiley and afternoon host Edith Bowman will move to weekend slots.
Elsewhere on the station, Early Breakfast presenter Greg James is heading to afternoons while Dev is shifting from Weekend Breakfast to the weekday Early Breakfast Show.
The Live Lounge continues in Fearne's new show with Radio 1 promising to bring more live music to daytime.
Fearne said: "I love being at Radio 1 and taking on a weekday show is a dream come true.
"Jo Whiley is leaving very big shoes for me to fill and it's nerve wracking. She has been a massive inspiration to me throughout my career so I have a high standard to live up to.”
As a result of changes to the weekday schedule, Edith Bowman will host Weekend Breakfast (7.00-10.00am); Jo Whiley moves to weekend afternoons (1.00-4.00pm); and Reggie Yates keeps the late afternoon slot (4.00-7.00pm).
Ben Cooper, Deputy Controller, Radio 1, said: "This is our first big shake-up of the weekday schedule for over five years.
"I feel it's the right time to make these changes in order to offer our listeners some exciting new programmes.
Andy Parfitt, Controller, Radio 1, added: "BBC Radio 1 must continue to change to connect with a new generation of audiences and this is a significant move, promoting three of our up-and-coming broadcasters into the heart of the schedule.”
The changes come into effect from 21 September 2009.
