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.
