NEW YORK – Miley Cyrus cautioned viewers she wouldn't be twerking on "Saturday Night Live." But she commanded the stage on this week's edition of the NBC sketch comedy show, serving as both host and musical guest.

And she did some shimmying as an oversexed U.S. Rep. Michele Bachmann in a parody video about the government shutdown.

Cyrus seized attention and criticism in August for her sexually charged MTV Video Music Awards performance, which featured the singer in scanty garb while exhibiting suggestive twerking gyrations. During Saturday's open, Cyrus made sport of the hubbub surrounding her racy display. She joked that she used to think twerking was cool, but changed her mind now that white people are doing it.

Besides her sketches, she performed two songs. Her album, "Bangerz," is out Tuesday.

Fox's kelly moves to prime time: Ask Fox News Channel's Megyn Kelly how her new prime-time program will differ from the edgy news show she had been hosting in the afternoon and she says that "it's going to be dark out." The joke has a serious point. Don't expect Kelly to turn into a fire-breathing partisan because she has more exclusive real estate. "If you watch O'Reilly, you hear a lot about what Bill O'Reilly thinks," she said. "Sean Hannity, same thing. But you're not going to hear what I think." "The Kelly File" is the linchpin to the first overhaul of Fox's prime-time lineup since 2002. Starting Monday, Hannity moves back an hour to 10 p.m. to make room for Kelly at 9, Greta Van Susteren shifts to 7 p.m. and Shepard Smith becomes a roving news anchor.
