The Beckhams aren’t the celebrity family with a new addition to celebrate. Actress Kate Hudson gave birth to a baby boy Saturday in Los Angeles.

The newborn’s father is Hudson’s fiance, 33-year-old Muse front-man Matthew Bellamy, who Hudson has been engaged to since April of this year. Hudson, 32, already has a 7-year-old son named Ryder Russell with her ex-husband, Black Crowes front-man Chris Robinson (SN: Hudson has a thing for rock band leaders, eh?)

Hudson, who didn’t want to know the sex of her unborn baby until its birth, announced that in January that she and Bellamy were expecting. She originally thought she was having a girl … but obviously nature had other plans for Hudson and her fiance because the couple welcomed a boy.

This is Matthew Bellamy’s first child.
