The stars were in bloom Tuesday afternoon in Los Angeles as Emmy Rossum, Camilla Belle, Alessandra Ambrosio, and Dita Von Teese celebrated the launch of Christian Louboutin's chic new Passage handbag collection at an intimate luncheon at the Chateau Marmont. Flower crowns in springtime colors like fuchsia and poppy graced the heads of red-soled-sporting attendees, who feted the label's fall/winter 2014 designs at the stylishly cheery event.

Handbags from the new Passage collection—which features classic, structured designs in bold hues like cherry red and eye-catching patterns like leopard and croc—were placed among bright blossoms that covered the tables, which made for truly fashionable decor. Spring had definitely sprung!
