It's official: 24-year-old model Hannah Davis (aka Derek Jeter's girlfriend) landed the highly coveted cover of this year's Sports Illustrated: Swimsuit Edition.

Davis posted the good news (and risqué cover) to her Instagram account with the caption: "Thank you to my @si_swimsuit and@imgmodels family! I am honored to be your 2015 cover girl! Wow!!"

The annual issue's cover girl was revealed late Wednesday on "The Tonight Show With Jimmy Fallon."

"I told my mom there was no way I'd get the cover," a surprised Davis told Sports Illustrated after the big reveal. "I told her, 'They do beaches for covers and I'm on a farm. There's no way. It's not possible.'" 

"I've always enjoyed the whole Swimsuit experience, and said that anything extra — a little square on the cover or anything like that — was a bonus," Davis added. "But still, this was my dream."

For Sports Illustrated's 50th anniversary last year, the magazine chose a cover with three models. Chrissy Teigen, Nina Agdal, and Lily Aldridge all made the cover.

Teigen tweeted late Wednesday after the Davis announcement:
