Kate Hudson joined Matthew Bellamy and big brother Ryder Robinson for lunch at A Votre Sante in Brentwood Friday. Kate was out and about after giving birth to her second son just last weekend. Kate Hudson and Matthew Bellamy welcomed Bingham Hawn Bellamy in LA on Saturday, though it took the couple a few days to decide what to call their new baby. They finally landed on Bing, which is from both Matthew's mother's maiden name and Kurt Russell's father's name, when Matthew tweeted about the arrival of his first child. The new family of four will have a few more weeks together before Matthew heads out of CA to continue his tour with Muse in August.
