Obama will grace the cover of next month's "shape issue." The April shape issue has been a Vogue tradition for the past decade. It focuses on what the magazine describes as -- the beauty and well-being of women's bodies.
Actresses Brooke Shields, Scarlett Johansson and model Gisele Bundchen have graced previous April covers.
The first lady last appeared on Vogue's cover in March 2009.
