The 27-year-old actor, who is engaged to Klaxons musician James Righton, is bemused by speculation that she is pregnant and said that the regular questions have made her worry about her figure, reported Femalefirst online. “People keep trying to make me pregnant! I’m not ready for it. Yes, I’d love to at some point, but not this quick,” said Knightley. “I have been asked whether I am pregnant yet about four or five times. And I started thinking, ‘Do I look like I’m pregnant ... I’m a very thin girl, I am sure I don’t look pregnant!’ It’s the ring on my finger,” she added.
