Kate Winslet is pregnant.

The 37-year-old Contagion actress - who has a 12-year-old daughter, Mia, from her first marriage to Jim Threapleton, and a nine-year-old son, Joe from her second marriage to director Sam Mendes - has confirmed she is expecting her first child with her husband Ned Rocknroll.

"Kate and Ned are delighted," a spokesperson for the couple said.

The Oscar-winner, who tied the knot with Ned, who is the nephew of Richard Branson, in a secret ceremony in December, previously revealed she was eager to have at least one more child. In an interview with InStyle in 2006, she said, "I'm hoping to have more kids. I don't know whether one or two. Oh, God, I would love to have more."

An insider recently told Star magazine that Ned, 34, was desperate to be a father: "Kate knows how much Ned wants to be a father. She thinks they would have the most adorable kid together, so they're planning on getting pregnant by the end of the year. Having a child together is her absolute priority."
