The 'Music and Lyrics' star pretended to be the former Spice Girl and insisted she wouldn't eat "meat, vegetables, grains, liquids or dairy products" for a sketch on US TV show 'Saturday Night Live' - but Victoria failed to find it funny.
A source says : "Going to America is a fresh start and she doesn't want to be seen as the poster girl for eating disorders. Victoria doesn't have an eating disorder, and wants to be a good sport, but it's just not funny to her."
Victoria and her soccer star husband David Beckham are moving to live in Los Angeles this summer after David signed a £128 million deal to play for Los Angeles Galaxy.
