The 27-year-old actress, who is engaged to Klaxons musician James Righton, is bemused by speculation 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, stop trying to make me pregnant," Knightley said.
"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.
