X Factor mentor Louis Walsh has claimed that John and Edward could win the show – comparing them to Madonna and Kylie – despite admitting the pair were not ‘the best singers or dancers’.

The twins are currently in rehearsals for next weekend’s show – preparing to perform their version of the theme tune to Ghostbusters.

Louis told Heat: “I think the twins can win it. They’re not the best singers or dancers, but they’re brilliant entertainers. Who cares whether they’re good singers or not? Madonna and Kylie aren’t the best singers either but like the twins, they are great entertainers.

“Every kid in every family is rooting for them. The kids like them and their parents don’t and they can rebel against them by voting for them.

“Viewers just want to see them. It’s the act they are tuning in to see. Without them the show would be boring.

“I am genuinely glad I picked them. I knew it was a gamble, but it has paid off. They work harder than anyone. They are living their dream and people love them. They are the best part of the show.”

The X Factor got 6.3 million more viewers than Saturday night TV rival Strictly Come Dancing last weekend.
