CBS orders 'Rock Star' sequel for summer but format still undecided January 17, 2006 CBS has renewed its Rock Star reality talent competition, ending months of rumors about whether the Mark Burnett-created reality series would return for a second season. But although CBS has now decided that the show -- along with co-hosts Dave Navarro and Brooke Burke -- will return as part of its Summer 2006 programming lineup, numerous other details about Rock Star's new season reportedly remain undecided, including whether the new season will center around finding another lead singer for a still-undetermined headless rock group.
