A "nervous and excited" Nick Grimshaw has taken over Radio 1's Breakfast Show.
The 28-year-old DJ, who replaced Chris Moyles after the end of his eight-and-a-half-year stint, welcomed listeners to a "a brand new breakfast show".
He said he would last in the job "just until the country uprises and I get thrown back to the night-time".
Grimshaw said he was "nervous and excited" but "desperate to get on with it" and kicked off his first show by playing Paris by Jay-Z and Kanye West.
He played a radio edit of the famously foul-mouthed track and joked that if he had played the full version it would have been "the world's shortest stint on the Radio 1 breakfast show - three and a half minutes".
Grimshaw, who admits he struggles with early mornings, said he set two alarms to make sure he got up.
He presented the programme on his own after station boss Ben Cooper said he wanted to move on from the "zoo" format of Moyles's show in which his production team played a large part, and is expected to double the amount of music.
Grimshaw, known for his posse of celebrity friends including Lily Allen, Alexa Chung, Miquita Oliver and Harry Styles from One Direction, was a surprise choice to many, with drivetime show host Greg James expected to be the next breakfast host.
