Model Ashley Graham will make history in this year's (15) Sports Illustrated Swimsuit Issue when she becomes the first plus-size beauty to grace the magazine.

The size-16 model will show off her curves in a swimwear ad for swimsuitsforall.

Wearing a tiny black bikini for the brand in the ad, she says, "I know my curves are sexy and I want everyone else to know that theirs are too. There is no reason to hide and every reason to flaunt."
