"I'm so incredibly excited to announce that I am on the cover of the 2016 issue of Sports Illustrated Swimsuit issue @si_swimsuit," she wrote. "Honestly words can't describe how grateful I am. I have worked my butt off and never gave up on my dream! Thank you so much for making my dreams come true tonight."
