Kate Hudson Backless Elie Saab Pictures at Stella's Birthday

Kate Hudson showed skin in a backless Elie Saab dress last night when she stepped out to attend Stella McCartney's 40th birthday bash. She brought fiancé Matt Bellamy along for the evening affair, though it seems the couple, who welcomed son Bingham two months ago, skipped out on attending the afterparty at the Groucho club. It was one of Kate's fanciest evenings out since she and Matthew had baby Bing in July. She completed her look with a pair of Jimmy Choo shoes and a sparkly accessory in her up-done hair.
