Kristen Bell and Dax Shepard hopped on the back of two beach cruisers and took to the streets of LA on Saturday. The pair rode around town and stopped for an occasional kiss. Kristen's back from a recent trip to South Africa, where she swam with sharks, and is gearing up for the Jan. 8 premiere of her new Showtime series, House of Lies. Her schedule is jam-packed with projects in the new year; in addition to narrating Gossip Girl Kristen's also starring with Drew Barrymore and John Krasinski in the whale tale, Big Miracle. Dax's acting career is right on track as well with a new storyline stirring up drama for his Parenthood character. Kristen and Dax have been engaged for almost two years and are clearly going strong, despite not sharing any wedding plans just yet.
