Olly Murs is Number One on the singles and albums chart this week you know.

'Troublemaker' (featuring Flo Rida, of course) is a non-mover on the singles chart, holding off the resurgent Bruno Mars and Rihanna who both climb seven places with 'Locked Out Of Heaven' and 'Diamonds', respect­ively.

Behind them are a lot of non-movers and at Number 10 is a new entry for street­piss advocate Ke$ha with 'Die Young'.

On the album chart, Olly 'scores' his second Number One album in a row with 'Right Place Right Time', which knocks Rihanna's 'Unapologetic' down to Number 3.

Girls Aloud's 'Ten' has to make do with the Number 9 spot, which isn't great to be honest, but is six places higher than Alicia Keys' 'Girl On Fire' and sig­ni­fic­antly better than the Number 21 new entry for McFly's Best Of or Kelly Clarkson's Number 24 start with 'Greatest Hits: Chapter One'.
