US TV bans Nigella bum camera shots?

Camera shots of Nigella Lawson's bum have been banned by a US TV network, say reports.

The celebrity chef has upset producers by eating too much and they are concerned viewers will turn off if they show pictures of her below the waist, according to the New York Post.

A source commented: "The result is a butt like a Budweiser horse. Her director is now doing back flips to not show her below the waist and deflects viewer vision by focusing on her cleavage, tongue and eyes more than ever."

Food Network has denied the accusations, claiming that the show was filmed in October 2007 and insisting no changes have been made since it was taped.
