Bottoms up!

Models Nina Agdal, Chrissy Teigen and Lily Aldridge are celebrating this Valentine’s Day by baring their booties on the cover of the 2014 Sports Illustrated swimsuit edition, which was released yesterday.

The cover features the gorgeous gals wearing only barely there bikini bottoms and posing together with their backs turned towards the camera.

“I’m speechless . . . This has been my goal,” said 21-year-old Agdal in a statement. “I couldn’t be happier to be on this year’s cover. It’s absolutely amazing!”

This is the second time Agdal has been featured in the sports magazine. Her shoot was so popular last year, she earned the “Rookie of the Year” title.

Not only did the models get the honor of being on the cover of the swimsuit edition, but this issue also marks the 50th anniversary of the magazine.

“I am so thrilled and honored to not only be on the cover but to be on the 50th Anniversary cover,” said Teigen.

“I am so incredibly honored to be part of this issue,” Aldridge stated. “As my first time ever shooting with Sports Illustrated I never imagined I would be on the cover.”

The cover was revealed on Jimmy Kimmel’s show last night and fans of the girls showed their support on Twitter.

Max George of the band The Wanted, tweeted words of encouragement for the model, saying “Fingers crossed for @NinaAgdal to get the new @SI_Swimsuit cover. You deserve it sweet! X.” The pair began dating last October, but recent reports suggest the pair has gone separate ways.

Teigen also took to Twitter to express her excitement.

I mean what else is there to say. I just cannot believe it. What an honor. Never, ever, ever have felt this kind of pure joy. Crazy crazy.
