Kate Winslet and Ned Rocknroll gave their newborn son a wild name: Bear!
The baby boy, born Dec. 7 in England, will take his mum's surname, the actress's rep confirmed to E! News. Bear Winslet (rather than Bear Rocknroll, which might have been a tad flashy for an infant) joins older half-siblings MIA, 13, and Joe, 10.
Kate, 38, and Ned, 35, quietly wed in December 2012. In June, the couple confirmed that they were "delighted" to be expecting their first child together.
