It's that time of year again! The highly-anticipated Sports Illustrated Swimsuit edition cover has been released and this year's lucky lady is ... Kate Upton (again)! Sports Illustrated chose the 20-year-old model for the second year in a row, revealing the cover via twitter with the comment, "POLAR BARE: @KateUpton in Antarctica is your 2013 SI Swimsuit Cover Model!" Brr, at least she gets to wear a jacket in that cold Antarctic weather... well, kinda.
In honor of this reveal, we take a look back at some of the best Sports Illustrated Swimsuit covers off all time! From Tyra to Bar, the Swimsuit edition cover has been graced by some of the most beautiful women in the entire world. Since its inception in 1964, some have credited Sports Illustrated with making the bikini a serious piece of apparel. To date, the best selling issue has been the 1989 issue featuring Kathy Ireland in Mexico wearing a yellow bandeau bikini.
