Bernadette, who with 19-year-old Ashford’s grandma and Sunderland star brother Fraizer Campbell donned Nu Vibe T-shirts for the show, said: “The boys have taken everything with a pinch of salt and are focusing on this week rather than what people are saying.

“Ashford’s been saying ‘come on guys, we can do this’ and they can’t wait for this weekend.

“This week they have been singing a completely different kind of song and they have absolutely stepped it up.

They are performing for the public vote and they are going to show the public what they can do.

“I really think they can go all the way and I hope that people in Huddersfield will pick up the phone and vote for Nu Vibe.”

As the band get used to their new-found fame, it was also announced this weekend that all of the finalists will perform on this year’s X Factor charity single, a cover of Rose Royce’s 1978 hit Wishing on a Star.

The song, expected to be recorded in London this week, will raise money for ATC and Children’s Hospice’s UK.

The charity’s aim is ensure that all life-limited and life-threatened children, young people and their families have the best quality care and support from the moment of diagnosis, wherever they live and for as long as the need it.

X Factor supremo Simon Cowell said he had worked closely with the charity, adding that having seen “the amazing work they do for kids and their families who need help and support I am thrilled that the X Factor charity single this year will benefit this charity.”
