He noted, too, that the cover is something Teigen has wanted for a long time. "She's been in the issue for several years now, and every year, it's been someone else," he said. "And this year it's her. We're very excited about it."

Teigen herself expressed her excitement on Twitter. "I mean, what else is there to say?" she wrote. "I just cannot believe it. What an honor. Never, ever, ever have [I] felt this kind of pure joy. Crazy crazy."
