Florida model Kate Upton, 20, has scored the cover of the Sports Illustrated swimsuit issue for the second year in a row.
The issue was officially unveiled Monday night during CBS' "Late Show with David Letterman."
The new issue marks the 50th anniversary of the series and hits newsstands today.
This cover marks Upton's third appearance in the swimsuit issue.
She was SI's "Rookie of the Year" in 2011 when Irina Shayk was on the cover.
This year the magazine sent 17 swimsuit models and photographers all over the world.
Upton's shoot lasted 10 days in Antarctica during December 2012.
When she returned to her home in Florida, Upton said she was "very, very sick. I don't think you can go to Antarctica and stand in a bikini without that happening. But I didn't die, and I'm OK now."
Upton called Antarctica "the most beautiful place I've ever been," but had advice for other people that might travel there, "You are definitely recommended to keep your clothes on."
