Two-time Sports Illustrated Swimsuit cover model Kate Upton has yet to reach her 21st birthday and may already be a household name.
Upton, who turns 21 in June, has now graced the cover in back-to-back years: in 2012 as Sport Illustrated Swimsuit's Rookie of the Year and again in 2013 with a photo from the first ever fashion shoot in Antarctica.

"It was an adventure for sure," Upton told CNBC in-studio Tuesday. "It's freezing there, obviously. No one knew what to expect. You had to go the land in these zodiac boats, kicking ice just to get the rafts through."
Upton, who hails from Florida, said she experienced hearing and eyesight loss after returning from the Earth's southernmost continent. "If I didn't get sick standing in Antarctica in a bikini, something would be wrong with me. I'd probably be Wonder Woman or something."
