Nick Grimshaw has said he was "nervous and excited" to take over Radio 1's Breakfast Show.
Chris Moyles has been given a send-off by showbiz pals including Ant and Dec who hosted a This Is Your Life-style farewell.
Nick Grimshaw has been handed the flagship Radio 1 breakfast show after Chris Moyles announced on air today that he was bowing out.
Nick Grimshaw has increased his Radio 1 Breakfast Show audience, but is still almost four million listeners behind his Radio 2 rival Chris Evans.
Grimshaw, who replaced Chris Moyles last year, saw his average audience reach 5.88 million according to industry body Rajar.
But is still less than Radio 4's Today Programme, which had an average audience in the second quarter of this year of 6.97 million, and way behind Evans whose average audience was 9.75 million.
Nick Grimshaw is set to inherit an audience of under seven million when he takes over the Radio 1 breakfast show in September.
The Chris Moyles show pulled in 6.9 million listeners in the second quarter of this year - down from 7.1 million in the first three months of 2012, according to figures released by audience measurement body Rajar.
Radio 2's Chris Evans easily beat Moyles in the popularity stakes with his breakfast show reaching an audience of 8.9 million, down from 9.2 million in the first three months.
Chris Moyles played a "cruel" prank on new breakfast host Nick Grimshaw today after he abandoned him in the studio live on air.
Grimshaw had been a guest on the flagship show and was talking about his appointment but Moyles and his team walked out, leaving the new host by himself.
The T4 presenter said: "Everyone's gone - this is not a hilarious on-air radio gag". He said Moyles had taken him for a drink last night and invited him on telling him they would have a "really nice morning together".
Grimshaw then told listeners: "I've only been up for 20 minutes. This is cruel, really cruel."
@grimmers AAAAAAARRRRRRRGGGGGHHHHHHHHH I knew it! CONGRATULATIONS!!!! You are going to be the best breakfast show EVER!!!!!! Well done! X
So happy for Nick Grimshaw :)
