> Nick Grimshaw: Ten Things About the new Radio 1 Breakfast Show host
"When I got the job, Kate said to me, 'What you wanna do, darling, is do what I do. Sometimes I go to work. Sometimes I go to work hungover. Sometimes I don't turn up at all. People love that. They don't know what to expect'," he told The Sun.
"I said, 'Kate, that's what Chris Evans did'. She said, 'Exactly, darling, everybody loved Chris Evans'. I said, 'Kate, they sacked him'."
Grimshaw, who officially replaces Chris Moyles on September 24, recently described his new job as a dream come true.
"The Radio 1 Breakfast Show is the only thing I've ever wanted to do since the age of 11," he said.
"So I feel like a witch now that it's happened. It's really exciting, it's something I've always listened to. From Sara Cox, I listened to on the way to school, and I've listened to Chris every day."
