The 2014 Sports Illustrated Swimsuit Issue hits newsstands today, featuring John Legend‘s wife Chrissy Teigen along with Nina Agdal and Lily Aldridge.

Jimmy Kimmel unveiled the 50th anniversary cover last week but when Chrissy first saw she’d made it after an SI editor revealed the cover to the three ladies, she revealed to On Air with Ryan Seacrest she exacted the exact same way as when John proposed to her.

“My first words to them were like, ‘Are you being serous?’ I’m on this weird thing where I think I’m being punked all the time when something great happens so I didn’t know if it was a joke. And I thought maybe Kimmel was playing one of his like famous pranks and I didn’t buy it.”

It’s real, Chrissy!

And in case you were wondering, Nina tells us the key to taking a great photo is to think of something that makes you happy.

“I think it’s a lot about catching something real … it’s about having an emotion and bringing that in to a photo.”
