Lady Gaga wears just a hat for a Vogue photo-shoot

Lady Gaga is wearing nothing but a massive pink feathered hat in the beautiful picture shot by Mert & Marcus, which appears in the pages of Vogue's 2012 September issue, marking the 120th anniversary of the magazine. The hat is designed by the legendary British milliner Stephen Jones.

The singer is also on the cover of the magazine, dressed in a purple Marc Jacobs gown.
