Helena Bonham Carter is pregnant. The "Harry Potter" actress - who has two children with her film director partner Tim Burton, Billy, five, and 20-month-old Nell - sparked rumors she is expecting again after she was spotted wearing a succession of floaty outfits.

A source said: "Helena is definitely pregnant, and is really suits her. She has a neat little bump already, and seems to be glowing."

Daniel Radcliffe braved torrential rain and hail at the world premiere of "Harry Potter and the Half-Blood Prince" in London's Leicester Square last night.

The 19-year-old star spent an hour signing autographs for some of the 3,000 screaming fans who had been camping next to the red carpet for more than 24 hours.

Guy Ritchie was mobbed by admiring women at the Empire Awards on Sunday. The "Snatch" director admitted he has been enjoying single life since his divorce from Madonna at the after-party for the British movie magazine's annual ceremony.

He said: "I'm single again - and I wouldn't have it any other way. I'm loving it at the moment. This is what I've been missing."

Helena Bonham Carter admits pregnancy made her defensive about her vices. The 42-year-old actress - who has two children with partner Tim Burton, son Billy, five and 13-month-old daughter Nell - found it impossible to give up coffee while pregnant, and developed a sharp retort for when she was criticized for succumbing to her caffeine cravings.

According to "The Black Book of Hollywood Pregnancy Secrets," if a man condemned her for drinking coffee, Helena would swiftly reply: "You try nine months of gestation and self-abnegation before you start censoring my diet.

Helena Bonham Carter and Tim Burton have named their daughter Nell.

The couple - who welcomed their first daughter into the world eight months ago - previously never disclosed the baby's name, but Helena has now confirmed she decided to call the child after "all the Helens in the family."
