Looks like Beyonce (or Sasha Fierce??) is the lucky June Marie Claire cover girl. The mag reports that costume designer Thierry Mugler designed her show attire for her world tour. Could this be a first for a magazine to not feature a runway/commercial designer on their cover? From the looks of the behind the scenes shoot, its a definite possibility that Ms. B could be showing off her costumes on newsstands front and center.
