Actress Kate Winslet is expecting her first child with new husband Ned Rocknroll.
The pair will greet their new arrival at the end of the year, Winslet's publicist Sara Keene said.
"I can confirm Kate Winslet is pregnant and she and Ned Rocknroll are thrilled," she said.
"The baby is due at the end of the year."
The 37-year-old actress married Mr Rocknroll, 34, the nephew of Virgin tycoon Sir Richard Branson, in New York in December, almost 18 months after they met.
The Oscar winner has two children from her two previous marriages.
She married director Jim Threapleton in 1998 and two years later the couple had a daughter, Mia, now 12.
Following their split in 2001, Winslet began a relationship with American Beauty director Sam Mendes, and they married in 2003. Their son Joe, nine, was born the same year and the couple separated in 2010.
Kate Winslet and Ned RocknRoll have explained why they sought legal action to prevent "embarrassing" photos of him at a fancy dress party from being published in the press.
The couple issued a statement after a High Court judge blocked The Sun from printing the images from 2010.
We have stopped The Sun from publishing semi-naked photos of Ned taken by a friend at a private 21st birthday party a few years ago. The photos are innocent but embarrassing and there is no reason to splash them across a newspaper.
We recognise that in the internet age privacy is harder and harder to maintain. But we will continue to do what we can, particularly to protect Kate's children from the results of media intrusion. We refuse to accept that her career means our family can't live a relatively normal life.
A High Court hearing will continue tomorrow on the bid by the new husband of Oscar-winning actress Kate Winslet to stop The Sun printing photographs taken at a private fancy dress party with an "outrageous" theme.
Kate Winslet's new husband Ned RocknRoll has today asked a High Court judge to stop The Sun from publishing old photographs of him at an "outrageous"-themed fancy dress party.
Mr RocknRoll, who changed his birth name of Abel Smith in 2008, said there was no public interest in the tabloid printing the private pictures, which were taken more than two years ago, as he was not a role model and was a "relative nobody" at the time.
Lawyers for The Sun are expected to contest Mr RocknRoll's application later today.
The newspaper said Mr RocknRoll, a marketing consultant and nephew of tycoon Sir Richard Branson, obtained a temporary injunction last week.
Oscar-winning actress Kate Winslet, 37, who achieved worldwide fame for her role in the 1997 blockbuster Titanic, will receive a CBE today for services to drama.
The actress said: "I feel deeply proud to receive this, as a part of an ever-expanding community of British actors and film-makers who are fortunate enough to be able to contribute to an international industry. This makes me very proud to be a Brit."
Actress Kate Winslet has said that acting in Titanic was pivotal to her career, at the red carpet 3D re-launch of the film. She said the film "opened doors to opportunities that would not have been there".
