Katie Holmes can't be Jackie O, but she can still dress like her. She has just signed on as the face of the new 2011 spring collection of Ann Taylor. The wife of actor Tom Cruise, Holmes will sport classic cut trousers and blazers and will be photographed by famed photographer Tom Munro. Holmes was supposed to play the role of Jacqueline Kennedy Onassis in an A&E eight-part series, but the network canceled the show under pressure from the Kennedy family. Previous celebrities featured in Ann Taylor ads include Naomi Watts and Heidi Klum.
