Actress Winona Ryder has shocked Hollywood by announcing her engagement to rocker BLAKE SENNETT. Ryder and Sennett revealed their news to guests at the Valentino show that marked the end of Paris Fashion Week in France on Thursday (28Feb08) - before most of the world even knew they were dating. Ryder and Rilo Kelly guitarist Sennett met on the set of new movie Water Pill. It's not the actress' first fling with a rocker - Johnny Depp's former fiancee has enjoyed high-profile relationships with a number of musicians, including Soul Asylum's Dave Pirner, Counting Crow's Adam Duritz, Foo Fighter Dave Grohl and Jamiroquai's Jay Kay.
