Dermot O'Leary has revealed that there are a lot of Glee-style groups on this year's 'X Factor'.
According to The Sun, he said: "We owe a lot to Glee as we're not seeing your typical girl and boy bands."
"JLS were by far the best band we've had, but this year the groups have started to do something different."
'The X Factor' returns to television screens Saturday 21 August.
