Nick Grimshaw has told listeners that he is leaving BBC Radio 1 after 14 years at the station.
Posting to Twitter, he wrote: "Some news I can finally share after giving it some thought for a while....I have decided that after 14 years on air it's time for me to leave Radio 1.
"It was my childhood dream to work here and I have truly had the time of my life. But now is time for a change.
"I want to thank you, the R1 listeners for joining me on this journey.
"Thank you for being a massive part of my life and sharing your lives with me on the radio every day. Thank you for providing endless hilarity, passion and an unquenchable eagerness to 'avvvvv it!"
The 36-year-old has been working for the BBC since 2007 and is expected to announce the news on his Drivetime show today.
Grimmy is believed to have told BBC bosses some weeks ago that he would be leaving, with reports claiming they have now appointed Jordan North and Vick Hope as his replacements.
A source told the Mirror: "Grimmy has loved every minute and done everything he ever dreamed of on Radio 1. It has been a really hard decision but he is looking forward to the next chapter in his life."
The anonymous source continued: "Grimmy will be a really hard act to follow but bosses are delighted that Jordan and Vick have agreed to team up as part of a new look Drivetime.
"They both can't wait to get started and jumped at the chance to step into Grimmy's shoes in such a high-profile slot.
"They've both earned the chance to reach a much bigger audience and fully intend to grasp what is a brilliant opportunity."
