Diana Vickers - X Factor 2008

X Factor finalist, Diana Vickers is said to be acting like a spoilt diva behind the scenes of the ITV talent show.

She is reported to be upsetting both staff and contestants alike by her constant demands and grumpy behaviour.

A source told The Daily Star: “Diana comes across as really angelic and sweet on the show, but she makes a bit of a fuss.

“Most people behind the scenes think she needs a bit of a kick up the backside.

“She doesn’t like being filmed before she has her makeup done and the constant cameras in the house that the finalists share.”
