"Sports Illustrated's" swimsuit issue will have not one, not two, but three different covers.  For the first time, three different models will grace the cover of the magazine and each is very different.  MMA star Ronda Rousey will be featured on one cover. 

Say hello 👋🏼 to 2016 #SISwim cover model @rondarousey! The best part, she's one of three.

Model Hailey Clauson will appear on another.  The third will show Ashley Graham, one of the magazine's "rookies" for this year.  Graham was announced last week as the first "plus-size" model to appear in the annual issue, though she prefers to be called "curvy."  She's previously appeared in the magazine for ad campaigns, but never as one of the "SI" swimsuit models.  This year's issue hits newsstands Monday.
