Laid Back (Extended Mix) Roger Horton
They're both playing Capital FM's Summertime Ball 2013, they're both known as the cheeky chaps of pop music and they will head out on tour together this summer. Play Capital's new quiz game and see just how easy it is to tell the artists apart.
Both stars always look their best on the red carpet and are never seen with a stitch out of place. But who was suited and booted in this number for the BRIT Awards this year?
Both stars love to move about on stage with arms and legs flying all over the shop. But whose limb was picking out one of their top fans in the crowd in this shot?
They're two male stars who love the mic and the mic stand. Who is making the most of the prop in this shot?
Hats off to anyone who gets this one, because the flat cap is a standard accessory in both these star's wardrobes.
It's OK if you can't quite figure this one out...but go on... have a guess!
The suit isn't just for the red carpet - it's for the stage as well. Can you name who opted for a grey two-piece for a live show in this picture?
Neither star is afraid to flash the flesh on stage - but which of the two cheeky chaps is giving fans a peek of their chest after getting all hot and sweaty?
It's possibly the thing the pair talk about just as much as music - their love of football. Both were seen taking part in the Soccer Aid charity match last year... but whose boots and athletic legs do these belong to?
Robbie Williams of England warms up ahead of the Soccer Aid football match, which sees an England team
Give us a song Robbie...or is it Olly? Robbie? Olly? Can you figure it out?
It's another chance for one of the stars to get up close and personal with the mic stand, but whose got their hands all over it this time?
They're two of pop's most eccentric and energetic stars, but whose taking a tumble for this shot? (P.s. Nice pink trousers).
