Kate Middleton is being quietly hounded to appear on the next cover of U.S. Vogue by none other than the editor herself, Anna Wintour. 

According to the New York Post's Page Six, a source said Wintour has been quietly but persuasively campaigning to get the new Duchess of Cambridge on the cover of the U.S. edition of Vogue.

Wintour reportedly has the help of Mario Testino to recruit the hotly-pursued Middleton for the cover, since he is a family friend. Testino was also the chosen photographer who shot William and Kate's official engagement photos released earlier this year in addition to countless shoots with the royal family, including Princess Diana of Wales.

Anna has been speaking to Mario about winning over Kate. She is really pressing him to shoot Kate for the cover, an unnamed source told the Post.

Middleton has stayed out of the magazine world's limelight, as she rejected an offer from British Vogue editor Alexandra Shulman to grace the cover of the UK edition before her wedding, New York magazine reported.

While using Testino as an important pawn to coax Kate into posing for the cover of American Vogue, Wintour and her team must first get approval from Buckingham Palace, which is quite protective over Middleton, according to the Post.

Following the royal wedding, Kate appeared on the cover of Grazia, which publically admitted to using Photoshop to digitally alter Middleton's waistline.

However, Kate Middleton could possibly accept the offer from Anna Wintour to land the cover of American Vogue since William's mother Princess Diana appeared on the cover for British Vogue four times between 1981 and 1997, according to The Stir.
