Same Difference brand Diana "standoffish"

Rex Features

Same Difference have called Diana Vickers "standoffish" after meeting her backstage at The X Factor.

The brother/sister duo spent time with this year's X Factor final six before performing on the show on November 22.

"We gave everyone a rose and a card backstage just to say good luck, because Leona did that for us last year and we thought it was really sweet," Sarah Smith told DS.

"Alexandra [Burke] came over and just started screaming and hugging us, it was mental."

However, they were disappointed by the reception they were given by 17-year-old Vickers, who has since progressed to the semi-finals of the ITV1 singing contest.

"Diana I have to say was a bit quiet and standoffish," Sean Smith said. "She certainly didn't do anything bad, but she didn't show us the same love everyone else did."

Sarah added: "Maybe she's a bit cool for school?"
