"It's especially awesome after how long it's been since my first cover," the former Desperate Housewives star, 38, told the magazine after receiving the honor.
"I've had a beautiful relationship with Maxim over all these years … When someone sees the cover of this issue, they're going to say, '¡Que rico!' … Say it when something is really good."
Speaking of really good, Longoria says she's an ace in the kitchen.
"One thing people are usually surprised about when they get to know me is how domestic I am," she explains. "So when you see the sexy Maxim cover and then you put it against me in an apron with flour in my hair, it takes a moment to reconcile that image."
But that's not all. The multi-talented actress, producer and philanthropist recently received her master's degree and had just presented her thesis at the time of the interview.
"Back in high school I really was the chameleon, too," she says. "I got along with the honors math club, then I would go to cheerleading practice, and then I was a band geek as well."
