ACCRINGTON’S Diana Vickers has done it again - singing her way into the next round of X Factor.

And the 17-year-old and her X Factor competitors woke up Monday morning to the news they have their first number one single.

The charity track Hero sold a massive 313,244 copies in six days making it the fastest selling charity single of the decade.

Proceeds from sales will go to Help For Heroes and the Royal British Legion Poppy Appeal for wounded troops.

During Saturday night‘s show Diana sang Blondie’s Call Me again wowing judges and celebrity fans alike.

Judge Simon Cowell was critical of the choreography around her but said she managed to make a difficult genre of music work for her.

He added: “You are proving yourself to be a very adaptable singer.”

Danni Minogue said: “I agree with Simon in that Diana and disco should not mix but you were the hottest disco darling I have ever seen. I loved you belting out the choruses. It really suited you.”

But Louis Walsh said: “The show was built around you and I woud like to see you dancing some week.”

Diana‘s mentor Cheryl Cole was quick to point out X Factor is not a dancing competition but a singing competition.

And special guest Will Young, who won the original Pop Idol in 2002, said his favourite performance of the night was Diana’s.
