British actress Kate Winslet is pregnant with her third child and first with husband Ned Rocknroll, a spokeswoman for the Oscar winner said on Tuesday.

Winslet, 37, gave birth to a daughter in 2000 with film director Jim Threapleton and a son in 2003 with film director Sam Mendes.

The "Titanic" star, who won an Academy Award for her role as an aging former guard at a Nazi concentration camp in 2008's "The Reader," married Rocknroll last December. Rocknroll, who was born Ned Abel Smith, is the nephew of British entrepreneur Richard Branson.
