Kate Hudson gave birth to a boy on Saturday night, sources have confirmed. It's her first child with fiancé and Muse frontman Matt Belamy. It's safe to say that the newborn and his older brother Ryder will have music in their genes. Hudson apparently has a thing for rock stars, though things didn't work out between Hudson and Ryder's father Chris Robinson of the Black Crowes. Some time after breaking up with Robinson, the Oscar-nominated actress said she didn't think marriage was "necessarily the golden ticket," but she changed her mind when she met Belamy. "She's crazy about him... Kate and Matt are so adorable together," said a source.
