Keira Knightley has said that she has no problem appearing naked on-screen, as she does in her current movie 'The Edge of Love'.
Speaking at a press conference at the Edinburgh International Film Festival to promote the John Maybury-directed film, Knightley said: "I always bare my breasts. It's not like it's only in this film!"
The 23-year-old also appeared naked in her last film, 'Atonement'.
Referring to a scene in 'The Edge of Love' alongside Irish star Cillian Murphy, Knightley said: "It was very simple. It was a sex scene and I never like them when they've got bras on."
The film was written by Sharman Macdonald, Knightley's mother, who says her actress daughter was the inspiration for writing the period romance that also stars
Sienna Miller and Matthew Rhys.
Knightley says that she was more uncomfortable with the fact that she had to sing in the movie, rather than having to appear naked.
She said: "I wasn't particularly pleased that Shar put singing into the script - in the first couple of takes I sounded like a pubescent boy."
'The Edge of Love' is showing from today in UK.
