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 participating in several sketches, she performed two songs.
Her album "Bangerz" is out Tuesday.
