'X Factor' judges tip groups for success

X Factor judges Louis Walsh and Cheryl Cole have become convinced that a group will win this year's series.

After sitting through a number of impressive auditions from bands, the pair have named the 'groups' category as their top choice to mentor.

"There are a few bands which are really hot this year," an insider told the Daily Star. "Louis and Cheryl think if they get them, they can win. They've been dropping hints."

A group has yet to win the ITV1 talent competition, which returns for a fifth series on August 16.
