Actress Kate Winslet has given birth to her first child with new husband Ned Rocknroll.

The British star's rep confirmed that she welcomed her third child, a son, at a hospital in Sussex, England, on Saturday.

"Mother and baby are doing great," the rep said in a statment.

The "Titanic" star married Rocknroll, who is the nephew of billionaire Richard Branson, in a ceremony in New York City last year. She has two other children, daughter Mia, 13, from her marriage to movie director Jim Threapleton; and son Joe, 9, with director Sam Mendes.

The couple chose to wait to share their happy news in order to avoid the headlines for a few extra days.

Winslet and Rocknroll met at Branson's Necker Island estate in the British Virgin Islands in 2011, during a trip when lightning struck the guest house she was staying in and set it afire. Winslet helped Branson's 90-year-old mother to safety.
