Members of One Direction are to co-host a show each on Radio 1 next month as they take over the airwaves for 10 hours.
They will join regular presenters throughout October 6 ahead of the station's Teen Awards, selecting the music and taking calls.
New breakfast show presenter Nick Grimshaw will be teaming up with his pal Harry Styles from the What Makes You Beautiful quintet when they do a two-hour stint from 10am.
To begin the day, Gemma Cairney will be joined by Liam Payne at 8am, while Scott Mills co-hosts with Zayn Malik from noon.
Huw Stephens takes a turn with Niall Horan at 2pm, handing over to Greg James and Louis Tomlinson at 4pm for the last of the two-hour shifts.
The group - soon to release new single Live While We're Young - will also be creating their own features for their shows.
One Direction will headline the Radio 1 Teen Awards - honouring inspirational teens and stars from entertainment and sport - at Wembley Arena the following day.
Nick will host the event with performances from Conor Maynard, Taylor Swift and Little Mix.
