Luckily the couple decided to give their baby boy her last name -- otherwise he would have Bear Rocknroll. Rar!

A spokesperson for Kate Winslet confirmed that the actress and her husband of one year, Ned Rocknroll, have named their newborn son Bear Winslet. The two welcomed their first child together on December 7 at a hospital near their West Sussex home.

Kate also has a son, Joe, with ex-husband/director Sam Mendes and a daughter, Mia, with her first ex-husband/director Jim Threapleton.
