Keira Knightley's On Set Chemistry  7/10/06

Keira Knightley was blown away by the on-set chemistry she felt with boyfriend Rupert Friend when they met while filming Pride & Prejudice.

The actress fell for the 23-year-old hunk, who played Mr Wickham in the Jane Austen classic, after splitting with on-off lover Jamie Dornan.

The Pirates of the Caribbean confesses that she had never felt that way about a co-star before.

Knightley says, "Normally it's ships passing in the night - you get incredibly close to people for a short amount of time, and often you never see each other again. But with this one we have really stayed in touch."
