Kate’s mom, Oscar-winner Goldie Hawn
, divorced Bill in 1980 and took up with actor Kurt Russell
three years later. Since then, Bill (who spent years as a pop idol in The Hudson Brothers) has been estranged from Kate and her older brother, actor Oliver Hudson. “When Kurt came on the scene … I became the big, bad wolf,” Bill has said. He’s blasted Kate for barring him from meeting her son, Ryder, whose father is rocker Chris Robinson of The Black Crowes, and her younger son, Bingham, with Muse frontman Matt Bellamy.
