Kate Winslet has given birth to a baby boy.

The 38-year-old British actress and her third husband, Ned Rocknroll, welcomed a nine-pound boy into the world at a Sussex, England hospital on Saturday, Breaking Celebrity News has confirmed.

This is the third child for the Titanic star who has daughter Mia, 13, with ex-hubby Jim Threapleton and son Joe, 9, with her other ex-husband, Sam Mendes.

The Labor Day star previously revealed she had enjoyed her third pregnancy more than the previous two.

She said: "I've been more active and healthier. I know more about how to take care of myself now. I think that between 27 and 37 was a big learning decade. I've been lucky - a bit tired and a bit sick at the beginning, but nothing major.”

The Oscar-winner also revealed in October that she hadn't decided whether she would take an extended break from her career when the baby arrived.

Kate and Ned, who is billionaire Richard Branson's nephew, tied the knot in a secret ceremony in New York City in December 2012.
