Miley Cyrus will be the subject of an hour-long documentary that will debut on MTV later this year (13). The pop star and actress invited the network's cameramen to follow her as she worked on her upcoming album - her follow-up to 2010's Can't Be Tamed. MTV's president of programming, Susanne Daniels, says the film will spotlight Cyrus' transition from "Disney princess to legitimate artist and fashion icon". Meanwhile, MTV bosses have also confirmed they've ordered a second season of Ke$ha's Crazy Beautiful Life docu-series. The six-part reality series premiered earlier this year (Apr13).
