Victoria Beckham turns guest editor for Glamour

Singer-turned-designer Victoria Beckham can now add fashion journalist to her list of credentials, as she has become US Glamour's first-ever guest editor for its September issue.

The British celebrity appears on the September 2012 cover wearing a tiara in a bubble bath, and in the accompanying interview she talks about her work, marriage and experience of guest editing -- notably coming up with her ‘fashion don'ts' for the publication.

"It's been exciting for me to see my ideas come to life, from type colors to photo selection to casting," explained the star.

"I even made my own list of Glamour fashion Don'ts to keep out of the issue: boat shoes (unless of course you're designer Alber Elbaz or on a boat!), Bermuda shorts, nose rings, Crocs, and American tan tights (that's nude pantyhose to you)."  

The star also discusses her famous pout, arguing that her signature look has developed in correlation with the rise of her eponymous clothing line.

"I actually used to smile a lot in pictures. I think I only stopped smiling when I got into fashion. [Laughs.] Fashion stole my smile! I've created this person. And I'm not saying that's not me, but I wouldn't say that's the whole me.... It's an armor that goes up," she mused.

Known as the most significant edition of any fashion magazine, publications regularly look to put the biggest stars on the covers of their September issue -- with other already revealed covers for September 2012 including Karlie Kloss on the covers of both Vogue Japan and British Vogue, and Keira Knightley for the September issue of Harper's Bazaar UK.
