Vogue magazine seems to be really impressed by Michelle Obama's sense of style over the years and her flawless appearance in a Jason Wu gown at the 2013 Presidential Inaugural Ball. Rumor mills are abuzz that the first lady might once again appear on the cover of the magazine's March issue as its crew was spotted in the White House, Jan. 31, according to Washingtonian.

CBS news reporter and White House correspondent Mark Knoller too witnessed the magazine's crew lugging around cameras. Fuelling these rumors, he tweeted, "Today at the WH. No public events on the president's schedule today, though Vogue is bringing camera gear into the WH this morning."

It wouldn't exactly be surprising if she does appear on the magazine's cover again considering her sophisticated and elegant sense of style. The first lady has always been appreciated for her impeccable fashion sense and the way she carries herself during formal events as well as casual appearances.

Even during the 2013 Presidential Inaugural Ball, we could hardly keep our eyes off Obama when she donned the custom made halter-neck gown by Jason Wu and footwear by Jimmy Choo.

The 49-year-old had appeared on Vogue's cover in the March 2009 issue just after husband Barrack Obama was sworn in as President, reports the Daily Mail. The appearance made her the second first lady to grace the cover of the fashion bible after Hilary Clinton in 1998.

While celebs mostly utilize the services of stylists to outfit them , Obama selects her own outfits. Dressed in a magenta dress by Wu, she looked radiant and confident on the cover beside the words, "Michelle Obama the First Lady the world's been waiting for."

While rumors are afloat, the Vogue team hasn't confirmed the news.
