"Bruno's got the 'best voice..."

'Grenade' star Bruno Mars has got the best voice on the radio according to Paramore's Hayley Williams.

Hayley tweeted, "In my personal opinion, @BrunoMars has the best voice on the radio right now. Incredible. Not that you asked for my personal opinion..."

It's a great week for compliments for Bruno - he's been named songwriter of the year by Music Week.

Bruno's team - known as The Smeezingtons - were behind Cee Lo Green's 'Forget You', B.o.B's 'Nothing On You' and Travie McCoy’s 'Billionaire' as well as Bruno's own singles.

Bruno is currently at No 1 in the Vodafone Freebees Big Top 40 chart with 'Grenade'

Second place went to Norweigan producers Stargate, who brought us Rihanna’s ‘What’s My Name’ and Katy Perry’s ‘Firework’.
