Bonham Carter was in a relationship with actor Kenneth Branagh (with whom she appeared in several films) from 1994 to the summer of 1999. She then briefly dated actors Rufus Sewell and Steve Martin. In October 2001, she began her current relationship with director Tim Burton, whom she met while filming Planet of the Apes. She has appeared in all of his subsequent films. They live in Belsize Park, London, in adjoining houses with a connecting hallway, each part decorated and styled to suit their own personalities, because they felt they couldn't live 'together' but didn't want to live apart. They purchased the house when she became pregnant with the couple's first child, son Billy Ray Burton, who was born on 4 October 2003. At age 41, she gave birth to her second child, a daughter named Nell, on 15 December 2007 in Central London. She says she named her daughter Nell after all the "Helens" in her family lineage.
