Victoria Beckham has reportedly been labeled a "grade-A bitch" by the crew documenting her every move for her new US reality TV show.

Star magazine reports that staff working on the NBC programme have been left infuriated by her attitude.

A show insider told the mag: "We think she's full of herself and not very nice. She's very picky, demanding and rude. And she was mean to the assistants, too.”

However, it’s not just the crew working alongside Victoria that have been treated in such a manner: "She waltzes around with her icy attitude. People will walk up to her and say, 'Welcome to America', or, 'Good luck with the move', and she doesn't even stop to talk to them."

"The show is designed to make her a star in the States, but she's dreaming if she thinks that's going to happen. She's coming off as a grade-A bitch!"

The insider also claims that producers are worried the show is going to be a huge flop, as the former Spice Girl is so dull. "No one knows what to do with her to make the show interesting - she's so boring! Every suggestion the producers make, she rejects."
