JLS have advised this year's X Factor bands to be unique.

The UK pop scene currently contains a number of successful boybands - such as One Direction and The Wanted - and fellow established act JLS believe that new bands need to try something different in order to make an impact.

District3 and Union J are the only groups left in the 2012 competition but speaking to Digital Spy, Aston Merrygold said that because of the market's saturation and variety, they need to be original. He said:

"Those two boybands are going to have to come out with something extremely different from what's in the market now. You've got the likes of us, The Wanted, 1D...Lawson. You've got a total mix and it's going to be hard to find your own lane." 

The 'Evolution' star added: "They're going to have to try and come out with something different. That show does bring out the best in UK talent, you can't deny that."
