Matt Edmondson and Mollie King will be the new weekend BBC Radio 1 Breakfast Show hosts (Friday to Sunday, 6am to 10am), swapping with Dev Griffin and Alice Levine, from Friday 16 November.
Starting her Radio 1 career as a guest host on Matt's show, Mollie quickly made an impression on listeners, soon becoming a permanent member of the Radio 1 family in June when she co-hosted the 1pm to 4pm slot with Matt as part of the new weekend schedule.
The duo will be bringing their usual fun and games plus more to the mornings.
Dev and Alice will be setting their alarms a little later and fronting the 1pm-4pm slot, after Maya Jama's Greatest Hits (10am to 1pm).
The swap comes as both presenters have had a busy 12 months, with Alice becoming an international sensation with the My Dad Wrote A Porno podcast and Dev reaching the final of Celebrity MasterChef and most recently stepping in to host The 8th until the end of the year, with a permanent host to be announced in coming weeks.
They'll be bringing with them popular features like 'Kids Ask' which has previously featured the likes of Tom Hardy, Margot Robbie and Idris Elba.
Matt Edmondson told the Entertainment Gazette: "Getting to present the Radio 1 Breakfast Show three days a week is an absolute dream come true, as is working with Mollie (a nightmare is technically still a dream). I know we're going to have so much fun, and I can't wait to get started."
Mollie King said: "I'm absolutely blown away to have been asked to host the Radio 1 Breakfast Show every Friday, Saturday and Sunday with Matt Edmondson, my partner in crime!
"I remember the buzz I got when I first walked into Radio 1 as a guest 10 years ago, and that buzz is still with me now every time I step through the studio doors. I can't wait to get started! See you there – bright and most definitely early!!"
Dev and Alice said: "The thing we will really miss is setting that 4am alarm, but in time we think we might get used to it. We love doing the show together, and the afternoons have such a good energy about them – these shows are ideal for our sense of humour and the kind of things we like to talk about. We can't wait to get started!"
Ben Cooper, controller at BBC Radio 1, said: "Radio 1 loves discovering new talent for the BBC and the industry, and Matt and Mollie along with Dev and Alice have been hugely popular with our listeners, on radio, on video and on social."
- You can listen to both shows on BBC Radio 1 or BBC Sounds from November.
