Pride and Prejudice star Keira Knightley has been planning her wedding with lover Rupert Friend.

The actress attended a party hosted by Lindsay Lohan in London on Friday, where she happily spoke about her dream of tying the knot with Friend in an Italian castle next year.

One guest told the News of the World: "She looked radiant and seemed to want the world to know that she and Rupert had got engaged. She was kissing and cuddling him all night. They were with six friends and were obviously in a celebratory mood after getting through five bottles of Dom Perignon.

"Keira couldn't stop giggling. She even told the waiter: 'Please get my husband a drink.' Even her girlfriends referred to him as her future husband."
