Kim Kardashian's controversial Vogue cover is flying off the shelves.

According to the New York Post newspaper, the issue is expected to sell between 300,000 and 400,000 copies.

Meanwhile, Beyonce's March 2013 cover sold around 355,000 copies, and a cover starring Michelle sold just under 300,000 copies in April 2013.

However, a spokesperson for Vogue says the magazine "never comments on sales figures".

Vogue has come under fire from some subscribers for featuring Kanye, 36, and Kim, 33, in a wedding-themed cover shoot for its latest issue, with 'Buffy the Vampire Slayer' star Sarah, 37, boldly claiming she would cancel her subscription.

She wrote on Twitter: "Well......I guess I'm cancelling my Vogue subscription. Who is with me??? (sic)"

But esteemed Vogue editor Anna Wintour has defended her decision to feature Kim on the cover.

She wrote in her editor's letter: "Kanye is an amazing performer and cultural provocateur, while Kim, through her strength of character, has created a place for herself in the glare of the world's spotlight, and it takes real guts to do that. I think we can all agree on the fact that that role is currently being played by Kim and Kanye to a T. (Or perhaps that should be to a K?)."
