London, Jan 27 : Sienna Miller's photo on the cover of Vogue, back in 2007, was airbrushed for the actress was "too toothy" to grace the cover page.

In a behind-the-scenes documentary, The September Issue, Vogue editor Anna Wintour has revealed that the 27-year-old actress was too "toothy" and staff were worried she has "too many fillings" and "unruly hair".

The documentary shows how the actress was airbrushed for the shoot with famed photographer Mario Testino back in 2007.

They took one photo of her face and super-imposed it on a separate picture of her body.

However, the mag bosses are trying to avoid any rift.

"While some retouching is a fact for any cover, no one is more convinced of Ms Miller's beauty than Vogue," the Mirror quoted Head of communications Patrick O'Connell as saying.

"The fact she appeared on the magazine's September cover, our most important issue of the year, is a testimony to this truth," he added.

But the Factory Girl's people admit that she's "always" digitally manipulated.

"Sienna Miller is the first person to admit that her photos are always retouched - no one is ever that perfect," said her US publicist Leslie Sloan (ANI)
