Nick Grimshaw Enlists Harry Styles, Rita Ora And Cheryl Cole For Radio 1 Breakfast Show Ad (VIDEO)

We knew the bromance between Nick Grimshaw and Harry Styles ran deep, but we can say it has officially reached new levels after seeing the One Directioner sneaking around the DJ's bedroom while he sleeps.

But Harry isn't being a creep, he's just kindly waking up his best pal so he doesn't miss his first Radio 1 Breakfast Show.

A new advert to promote Grimmy ascending to the slot vacated by Chris Moyles on Friday, sees a whole host of his famous pals enlisted to help him with his morning routine.

En route to his show - which is "now with added music" (a dig at Moyles perchance?) - there's Professor Green the wardrobe assistant, Rita Ora the toast maker and Cheryl Cole playing the part of chief 'hurry-up'erer.

Now hopefully he can get just as many big names to appear on the actual show when he makes his debut next Monday.
