Spoiler alert: Rihanna is indeed on Vogue 's March cover. As if you didn't already know after photos from the upcoming issue leaked online last week and speculation began to build that the singer had landed her third U.S. cover. Donning embellished jeans and a sheer Louis Vuitton top. Inside the issue, Rihanna dishes on the personal fashion rules that create her signature style. "If I'm wearing a top, I don't wear a bra. If I'm wearing a bra, I just wear a bra."
