Kate Winslet Gives Birth To Baby Boy!

Kate Winslet has given birth to a 9lb baby boy with her third husband, Ned RocknRoll.

The actress welcomed her son at a hospital in Sussex on Saturday. He is her third child but the first for Ned, the nephew of Sir RIchard Branson.

A spokesman told the Daily Mail: "Kate had 'Baby Boy Winslet' on Saturday at an NHS Hospital," adding that that the new mother and husband Ned Rocknroll were "thrilled to bits".

The baby joins Mia Honey Threapleton, 13, and Joe Alfie Winslet Mendes, nine, from Kate's marriages to Jim Threapleton and Sam Mendes.

According to E! News, Kate's rep added: "Baby and mother are doing great."

The boy's first name has not yet been released, but it's been reported that he won't be taken on his 35-year-old father's out-there surname - he'll be a Winslet. *Sigh of relief*

Congrats to the new mum and dad.
