With all ears listening in on how Nick would fare it is perhaps no surprise that the DJ would enlist the help of his most famous friend.
Nick took charge of proceedings today following Chris Moyles' popular eight year stint on the show.
No stranger to appearing on Nick's previous radio shows, Harry was in good spirits despite the early wake up call.
On being asked if he was enjoying the show Harry joked: "What show? This show? Oh it's great!"

Nick's stunt to pull Harry out of bed clearly went down well with One Direction fans who flocked to Twitter to tweet their approval of the show.@unfthewanted tweeted: "If Nick Grimshaw was 1Ds management, the world would be a better place #NickGrimshawForNewOneDirectionManagement."
While Amanda DeSevo also approved saying: "waking up and listening to Nick Grimshaw's voice is something I could get used to. #teamgrimmy @grimmers"
And @Iam1Derfu also loved Nick so much she wanted to listen to him all day long writing: "why can't nick grimshaw's radio show go on 24/7 he's funny okay."
Paul Jones had a problem with the DJ's voice tweeting: "Cannot believe breakfast show is now with Nick Grimshaw, cannot stand his voice no longer a listener"
While Daniel Parr had a problem with the format of the show: "Nick Grimshaw more like Nick Grimshow #bringbackMoyles"
And Lewis Sutch disapproved of the choice of special guests posting: "So Nick Grimshaw's first morning show.... Bieber and Styles on the first morning? That tells me all I need to know. #NoThanks"
With the jury still out over on the Twittersphere, what did the critics think of Nick's first outing?
The Telegraph approved of Nick's performance stating: "Overall, this was a promising start — and a clear break from what went before. It was out with dad rock, cynicism and bloatedly self-indulgent banter; in with dance beats, youthful energy and enthusiasm for new music."
The Independent also gave him a glowing review saying: "His love of music, together with his showbiz friends, will only enhance the most prestigious show on UK radio."
As for us, we didn't think the show was vastly different to Nick's previous late night effort. Once the hype has died down and the celebrity guests become more B-List than A-List then we'll really see what Nick is made of.
