MTV is offering….an HOUR.  More below,

A Miley Cyrus documentary is coming to MTV this Fall — but unlike Ke$ha‘s documentary SERIES on the same network, Miley’s will just be a one-hour one-time thing.
According to the official announcement, “The film follows Cyrus as she works on [her new] album and delves deep into the transformation she has experienced over the past few years.”
Think of all the equity that Miley had built, with kids and tweens (thrugh Disney)…and now starting from scratch it seems (with a teen audience, anways) and taking a back-seat to…….Ke$ha?!?
