Former Doctor Who star Billie Piper has offered a bathroom tip to Hollywood actresses performing in period dramas - the easiest way to urinate in a corset. The 24-year-old recently donned 19th century costume for a TV adaptation of JANE AUSTEN's Mansfield Park and found toilet trips a little tricky. She recalls, "I've got a technique now about how you pee in a corset. You straddle the loo. You kind of climb over it and have the dress fall behind you. "You pee the same way that a guy would. It works really well."
