Scarlett Johansson has been named the Sexiest Woman Alive for the second time by Esquire magazine.

The Don Jon actress is the first person to win the accolade twice, having first received the title in 2006.

In the November issue of the magazine, she was asked why she wanted to accept the title of Sexiest Woman Alive, to which she replied: "You know, I gotta hustle. I'm a 28-year-old woman in the movie business, right?

"Pretty soon the roles you're offered all become mothers. Then they just sort of stop. I have to hedge against that with work - theatre, producing, this thing with Esquire."

Johannson, who recently became engaged to French journalist Romain Dauriac, also opened up about her relationship, saying that she thinks it ok to be jealous.

She explained: "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."
