While Cheryl Cole has never exactly had us ROFLing all over the shop, we always thought she owned a sense of humour.

Well, it seems it's gone AWOL after she stormed out of a BBC interview after they played a prank on her.

Cheryl had agreed to speak to a journalist from a BBC Three show at the Capital Summertime Ball recently, but was angered when they kept repeating the same question.

A source told The Mirror: "Cheryl was happy to chat to the BBC, but it was a bit odd when they started asking her, 'Why are we here?'

"She took it to mean, 'Why are we at this event?' So she said that she was here promoting her new single and performing.

"They repeated, 'Why are we here?' At that point, it seemed like a dig at her for not being worthy of being on the same bill as The Wanted and Jessie J.

"They repeated it again, this time saying, 'Why are we here on Earth?'

"There was a slight pause, and then Cheryl walked off. It was obvious by then they were being daft."

The interview is set to air on new prank show The Revolution Will Be Televised, so we will be able to see it in all its stroppy glory when it airs later this year.

Meanwhile, Cheryl has been busy building bridges with Girls Aloud bandmate Nadine Coyle.

Chez is reported to have invited the estranged member of the band over to hers for a girly night in to help mend their relationship.

A source told Heat magazine: "Cheryl likes socialising in her own house, it's more private and she knew it would be a good place for her and Nadine to talk things through in their own space.

"Cheryl told Nadine she didn't want there to be any animosity between them and that it was coming between the Girls Aloud reunion.

"The girls know they're very different people, and they'll never be best friends. But they'll put on a united front, and both Cheryl and Nadine are happy they had the chat."
