BBC Radio 1 Breakfast Show host Nick Grimshaw has revealed his frustration at Rihanna after she apparently cancelled an interview at the last minute.

The superstar singer is currently in the throes of promoting her new album 'Unapologetic' but it seems she didn't quite fancy being interviewed by Radio 1.

Grimshaw, who took over the coveted role from Chris Moyles earlier this year, said on air:

"I'm gonna have a tantrum because it's my favourite popstar. We're not even mentioning her. We're not gonna promote it now. We were kinda forced into having Rihanna as our Record of the Week because we were going to do a big interview with her but once it was cancelled we changed it."

He added: "She ruined my week. Nice one Rihanna."
