Ananova:

Know those "take a friend" to work days when you get to tag along and observe?

Well, we'd like to make a plea to Keira Knightley to spend a day on set with her.

Because after her chat about a certain male co-star getting his kit off...

We're intrigued to say the least.

Chatting to the Daily Mail, she's talked about her new movie, The Duchess, and the problems her character's clothing caused her.

She told the paper: "I had to be sewn in each time I put a costume on, and carefully unstitched when I took it off.

"Once you were dressed, that was it. No chance of a toilet break because there were too many layers of clothing and I was too wide to fit into a loo cubicle."

Nattering about a lusty scene with co-star Dominic Cooper, she said: "The urgency and the lust would have evaporated long before I'd got round to unlacing my final layer.

"So Dominic was told to take his kit off, which was easier for a man to do."

Sounds good to us.
