Keira Knightley panics when she thinks about planning her wedding.

While the 27-year-old actress is besotted with her fiance James Righton, she hasn't managed to put together any plans for their big day yet.

A source told Us Weekly: "She gets flustered when it is mentioned. She's getting ideas and trying no to stress. What matters to her most is being with him."

The 'Anna Karenina' star previously admitted she felt pressured by the media to rush into their marriage and have kids thanks to constant speculation as to whether she and her Klaxons musician beau are expecting their first child.

She laughed: "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.

"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!"
