'Sports Illustrated'' Kate Upton Flies = Literally = Onto Third Swimsuit Cover ''Photos''.

Kate Upton made the third time a charm. Well, actually, the first and second times worked out pretty well for her, too. But the busty 21-year-old model and reported girlfriend of Detroit Tigers star pitcher Justin Verlander has landed on the cover of the Sports Illustrated swimsuit issue for the third time.

This time, however, there’s a new wrinkle to the Kate Upton Sports Illustrated cover. The magazine, celebrating the 50th anniversary of its annual billion-dollar cheesecake extravaganza, has included a bonus back cover to go along with the three models who flash their barely-covered booties on the front.

So Kate Upton this time gets the back cover of the swimsuit issue. Eager Sports Illustrated readers, or perhaps in this case “readers,” will need to flip the magazine over to view this eye-popping pic of Kate Upton.
