Just The Way You Are will hit number one this Sunday as the LA-based star massively outsells his nearest rivals.

And Bruno says co-writing and producing massive hits for B.o.B and Travie McCoy this year (Nothin On You and Billionaire) has helped him gain fans.

Mars told MTV News: “For Nothin On You we were in the studio and we came up with that hook, then B.o.B comes in and just does his thing on the track. It was a dream collaboration.”

He continued: “Travie McCoy was the same thing, I played him the little part of Billionaire that I’d written and he said ‘I love it but I have to talk about what I want. I’m not gonna rap about cars and strip clubs.'

“I became great friends with both of them and they put me on it. People know me from those songs so thanks Bob, thanks Travie!”
