29-year-old Keira Knightley graces the cover of Glamour July 2014 issue. The British actress looks beautiful in a Altuzarra backless dress and cuff by the same designer on the cover of the magazine. Keira was photographed by Tom Munro.

The actress also shared her thoughts on self-doubt, happiness and marriage with the magazine and much more. Here is a sneak peek:

Doing a romantic comedy : “[W]ith a feel-good film you are always risking going way too cheesy….But maybe I can have a little holiday where I’m not playing a character who is being destroyed.”

Getting married : “[W]hen James proposed, I just thought, Well, never done that before. It seemed like a fun thing to do.”

Begin Again co-star Adam Levine: “He did play a d-ckhead very well. Actually, I admire him being so willing. To play a d-ckhead is quite a big thing when you are trying to break into film and you want to be likable.”

Self-doubt : “There are those who manage that time of their lives really well—doing a lot of partying and making a lot of mistakes and thinking the world is only there for you, but I was way too introverted, and there was always this sh-tload of photographers, who made it worse. When I hit 25, for some reason I didn’t care anymore—I allowed myself to chill out. Since then, everything’s been amazing.”
