Victoria Beckham - Beckham Upset After Missing Out On Vogue Cover

VICTORIA BECKHAM is reportedly devastated after learning she won't be gracing the cover of U.S. fashion bible Vogue - because she has already posed for the publication's main competitor.

The former Spice Girl is keen to make her mark on the fashion industry, and is proving a hit following the release of her first clothes line - even managing to persuade supermodel Elle MACpherson to don her expensive dresses.

The star is still seeking the approval of the heavyweights at American Vogue, and has been on a strict diet while sticking to haute couture fashion in a bid to impress magazine bosses and land the chance of appearing on the cover, according to a new U.K. report.

But Beckham has reportedly been snubbed by magazine editor Anna Wintour - because she has appeared on rival fashion publication Elle's cover.

A source tells Britain's Daily Mail newspaper, "Victoria hoped to land the Vogue cover but it fell through weeks ago. She posed for Elle instead and now Vogue won't consider her for at least four months."

The style icon has already appeared on the cover of British and Russian Vogue.
