X Factor star Alexandra Burke shocked partygoers with her excessive “diva” behaviour, a report has claimed.

Sources told a tabloid newspaper that the `Bad Boys’ singer had issued a number of demands during a recent private gig to celebrate the 30th birthday of Liverpool footballer Jamie Carragher’s wife Nicola.

An insider told the Daily Star: “She acted like a diva.

“She wouldn’t pose for snaps and made her manager walk 20 minutes for a specific brand of bottled water.”

It was recently reported that Burke was paid a fee of £10,00 to perform for the WAG.

A source told The Sun: “Nicola is a big X Factor fan so Jamie thought it would be fun to book Alex.

“He agreed to pay a five figure sum for her to perform a short set.”
