Actress Helena Bonham Carter has given birth to a baby boy.
The child, as yet unnamed, was born on Saturday in a London hospital, her agent said.
It is the first baby for the actress, 37, and her partner, film director Tim Burton.
The couple met when Burton, 45, directed her in Planet of the Apes and they have been together for nearly two years.
They live in adjoining houses in Belsize Park, north London, and only recently knocked an inter-connecting doorway between the two.
Joking about the unconventional living arrangement, she tells this week’s Radio Times: “I don’t know if we’ll marry. I find it romantic bearing his illegitimate child and living next door.”
Bonham Carter was previously in a five-year relationship with Kenneth Branagh, which ended in 1999.
She recently told how she feared she would never fall in love again and have a baby.
“I had a crisis when I was 35,” she said. “I thought, ‘I’m still single and I’m never going to meet someone.’
“I thought ‘Oh my God, I’ve got to hurry up.’ You start thinking more about babies when you get to my age. But if it hadn’t happened, I wouldn’t have known what I was missing, I guess.”
Of meeting Beetlejuice and Edward Scissorhands director Burton, she said: “Falling in love with him was completely unexpected. We are soul mates. I’m so relieved that it has happened with Tim. I know now that I couldn’t really be with anybody else.”
Bonham Carter found fame in the 1985 Merchant Ivory period drama A Room With A View.
She went on to star in Howards End, Fight Club opposite Brad Pitt, and The Wings of the Dove, for which she received an Oscar nomination.
The actress is soon to appear with Ray Winstone in ITV1’s lavish epic Henry VIII, in which she plays Anne Boleyn.
