Ashley Tisdale is moving on from "High School Musical" to considerably more sordid offerings.
Tisdale, who played Sharpay Evans in the Disney series of films, will guest star in a two-episode arc in FX's somewhat grittier motorcycle drama "Sons of Anarchy."
In an even further departure from her Disney past, Tisdale will play Emma Jean, a pricey escort who makes things complicated for the SAMCRO motorcycle club when she shows up on the scene.
The 26-year-old Tisdale, who will star in the upcoming "Scary Movie 5," joins a number of new additions for the series' fifth season, including former "Lost" star Harold Perrineau, who will play SAMCRO gang rival Damon Pope, and former "NYPD Blue" star Jimmy Smits, who will portray Neron "Nero" Padilla, a gang member who ends up mentoring newly installed SAMCRO president Jackson "Jax" Teller.
"Sons of Anarchy" was renewed earlier this year for a fifth and sixth season. The renewal came as part of an overall deal with "Sons of Anarchy" creator Kurt Sutter, which keeps him in control of the show and allows him to develop programs for both cable and networks.
