London: Actress Helena Bonham Carter had to wear a nappy on the set of `Harry Potter and The Half-Blood Prince` because she had a weak bladder after the birth of her second child.
The star started work on the sixth movie just 12 weeks after welcoming her daughter Nell.
But her high-energy scenes came too close to the birth, and she admits she had several accidents during filming. So, she resorted to wearing a nappy to save herself from embarrassing drying-off sessions, reports dailystar.co.uk.
"I really couldn`t jump up and down and scream without losing most of my bodily liquid. They had these air dryers on set, these huge things - that`s where I would dry myself off," said Carter.
She managed keeping the diapers a secret during the shoot.
"None of the men knew I wore diapers. They don`t know, you see. But all the girls were, like, `How can you?` But, actually, I don`t think I was too embarrassed. There`s something quite liberating about having a baby."
"I loved having a baby. I would have a baby every day if I could. The birth day is fantastic. It is magic. It is complete magic," she said.
