Michelle Obama’s second Vogue cover revealed

America's First Lady, Michelle Obama, was photographed by Annie Leibovitz for her second US Vogue cover.

Michelle Obama, who wears a blue dress by one of her favourite designers, Reed Krakoff, reportedly resisted Leibovitz's efforts "to entice [her] into one of her trademark creative shoots she's employed for so many Hollywood celebrities", reports the Washington Post . The photographer is known for her fantastical shoots which usually employ vast budgets, costumes, sets and often nudity .

The First Lady's second cover comes four years after her first, which was shot shortly after her husband was elected as President. But she's not the only President's wife to pose for the fashion bible - Hillary Clinton appeared on its December 1998 cover during her stint as the President's wife, and many others have appeared inside the magazine.

It's no great surprise that Mrs Obama, 49, agreed to pose for the publication again - editor-in-chief Anna Wintour was one of Barack Obama's foremost fundraisers during his re-election campaign - however Jonathan Van Meter, who conducted the interview inside the issue, said it took him three years to secure the interview with the couple.

Inside the issue, Michelle reportedly talks about her husband's lack of style and the amount of attention paid to her wardrobe choices - she is, after all, the first First Lady to receive so much coverage, and criticism, for her clothing.

Iran gives Michelle Obama's Oscars dress sleeves

Michelle Obama's brief video appearance at the Oscars proved too racy for Iran's state news agency, which took it on itself to PhotoShop the First Lady's shoulderless dress into a more modest outfit.

Mrs Obama appeared via video link at the Los Angeles award ceremony, wearing a shimmering silver dress by Naeem Khan as she announced that Argo had won the Academy Award for best picture.

The President's wife sometimes jokes about her right to "bare arms" and her dress left her shoulders and upper chest exposed.

But a report by Fars, an Iranian news agency that acts as a semi-official mouthpiece for the regime, told a different story. Its account of the Oscars ceremony was accompanied by a crudely-altered image of Mrs Obama in a less-revealing dress.

The alteration is believed to have been made so the photograph would comply with the strict rules enforced by Iranian media censors.

Iran has a history of digitally rescuing female modesty, and in 2011 a photograph of Baroness Ashton, the EU's foreign policy chief, was altered to raise the hemline of a relatively low-cut top.
