The pair's post-dalliance reconciliation and subsequent cozinesshit the skidsin May, when they broke things off after three-plus years of unsteady togetherness. Reunion rumors continued through the fall, despite the actor's rumored wooing of Dylan Penn, the daughter of Sean Penn and Robin Wright. As for Sanders, his wife, actress Liberty Ross, filed for divorce in January.
