It was also reported that Cowell thinks it would be a "disaster" if the 34-year-old Liverpudlian were to win the show.
Speaking on The Xtra Factor tonight (November 3), Barlow was asked whether it was true whether Cowell and Barlow had come to blows over the contestant.

Barlow said: "I don't know of any clash, I don't read newspapers."
He continued, saying that "there's been no clash", adding: "But whether something's been said backstage, I'm not sure."
