Scarlett Johansson is Esquire's 2013 Sexiest Woman Alive!

The "Don Jon" star graces the November cover of Esquire magazine where she opens up about her new fiance, taking some needed time off and aging in Hollywood.

The 28-year-old is at the top of her career, thanks to "Avengers," and she's the only actress to get the Esquire honor twice.

Talking about her fiance Romain Dauriac, ScarJo admits that he's the first man to ever make her feel jealous.

"I didn't think I was a jealous person until I started dating my current, my one-and-only. I think maybe in the past I didn't have the same kind of investment. Not that I liked my partner less, I just wasn't capable of it or caring that much," she says.

Sorry Ryan Reynolds -- that's gotta sting a little.

The actress -- who has been working nonstop in the last year -- says she's finally going to take some much-needed time off.

"I'm exhausted and this is my last day in the world," she tells the mag. "This is the last day, and this is the last piece of work. Then I'm taking a month-long vacation. But I'm not going anywhere, which just makes it more of a staycation. There's luxury in being near home. When you spend a lot of time, like I do, just standing around and waiting, or being moved from place to place, every minute gets consumed by something someone else has set up for you."

Scarlett plays the super sexy love interest of the porn-obsessed Joseph Gordon Levitt in "Don Jon." While she adores playing the bombshell, Scarlett believes her time is limited in the movie business.

"You know, I gotta hustle. I'm a twenty-eight-year-old woman in the movie business, right?" she says. "Pretty soon the roles you're offered all become mothers. Then they just sort of stop. I have to hedge against that with work—theater, producing, this thing with Esquire."
