Keira KnightleyKeira Knightley is adamant that she won’t go down Sienna Miller’s alleged route or Lindsay Lohan’s inevitable one of always getting romantically entangled with their co-stars because when she’s on the set, she wants to be seen as a professional.

Keira is currently dating Pride and Prejudice co-star Rupert Friend but insists they didn’t get together until after the filming had finished. She told In Style magazine: “I haven’t ever had an on-set romance with anyone.”

But that’s not to say she doesn’t think about Rupert while she’s working. She is currently filming Silk in Italy and is using her time over there to pick up a few phrases to impress Rupert.

She explained: “An Italian expression I have picked up is ‘Baciami, mio caro’, which translates as ‘kiss me, my darling’.”
