Kate Winslet has named her newborn son Bear.
The Oscar winner and her husband of one year, Ned Rocknroll, welcomed the new addition on December 7 in the UK.
It is the first child for Rocknroll, 35, and the third for Winslet, who has Mia, 13, and Joe, 10, from her two previous marriages.
The unusual baby name may not come as a surprise due to his father's unconventional surname - Rocknroll was previously called Abel Smith before changing his name - however a representative for Winslet confirmed the tot would be moving away from tradition to take his mother's surname.
Bear has become a popular choice for celebrity babies in recent years, with Alicia Silverstone naming her son Bear Blu and Jamie Oliver adding it as a middle name for his child Buddy.
