Cyrus hosted SNL on Saturday night, leading to an inevitable face-off between the 18-year-old singer and cast member Vanessa Bayer's parody.
But Cyrus appeared on Bayer's "The Miley Cyrus Show" not as herself, but 17-year-old Justin Bieber.
Cyrus played Bieber as too hip to use Bayer's enthusiastic "pretty cool" catch phrase.
In other sketches, Cyrus also played Fergie and Lindsay Lohan. Her Lohan impression occurred during a sketch with cast members portraying Charlie Sheen as the host of a TV show called "Duh! Winning!" with Lohan.
