NEW YORK - Kate Upton repeats as this year's Sports Illustrated Swimsuit cover model.
It's the second straight year she's been on S-I's cover.
The cover shot was taken in Antarctica, with Upton wearing only a white, fur-lined parka and a bikini bottom.
She says it's the most she's wearing in the whole issue.
The shoot spanned 10 days in December, which is Antarctica's "summer."
Upton says it's the most beautiful place she's ever seen.
When she returned home to Florida, Upton says she was "very, very sick" but is OK now.
Upton has this advice for anyone going to Antarctica, "keep your clothes on."
The 50th anniversary S-I Swimsuit issue goes on sale today.
