London, England (BANG) - Helena Bonham Carter and Tim Burton have become parents for the second time.

The actress and the director welcomed a baby girl into the world on Saturday and both mother and daughter are said to be doing well.

The couple's spokesperson, Karon Maskill, said, "They are absolutely delighted they have a daughter. It's a lovely Christmas present for the family."

The pair already have a four-year-old son, Billy, and Helena recently revealed she was very excited at the thought of him becoming a big brother.

She said, "I just can't wait. It's hard to imagine we can make anything other than Billy."

Helena, 41, recently revealed her breasts swelled to the size of "melons" while she was expecting.

The actress fell pregnant during the filming of Tim's new musical movie, "Sweeney Todd: The Demon Barber of Fleet Street", and revealed her breast size changes constantly in the final cut of the movie because it was filmed out of sequence.

Helena said, "Anyone who pays attention to my chest size will see there's no continuity. The first half of filming I wasn't pregnant, and the second half I was, and because we didn't shoot it in order, I start off with huge breasts and then I walk upstairs and suddenly I've got tangerines again. It's melons to tangerines!"
