Ronda Rousey, Ashley Graham cover historic Sports Illustrated swimsuit issue

Brace yourself for some serious heat -- Sports Illustrated has unveiled its swimsuit issue and it has everything.

Ronda Rousey covered in body paint! Ashley Graham in an ity-bity string bikini! Hailey Clauson in the old 'hand bra'!

That's right -- not one but three smoking hot women were selected for this year's honor, a first in the magazine's 52 year history. But the significance doesn't stop there. The choice to highlight Graham and Rousey is monumental; a major shift for an industry that has long held a narrow view of beauty. One that typically hasn't embraced Graham's size 16 curves.

Though SI has featured buxom models like Kate Upton and Tyra Banks in the past, putting a plus size model on the cover is new (and welcomed!) territory.

Graham also stars in a #SwimSexy campaign alongside 56-year-old model Nicola Griffin inside the pages of the magazine, making a compelling case for wearing a gold bikini at any age or size.

The issue will be available February 15, along with a series of VR content featuring former Swimsuit cover models Nina Agdal, Irina Shayk and Hannah Davis.
