High School Musical star Ashley Tisdale is leaving the Disney world behind her, landing a provocative guest-starring arc on the FX series Sons of Anarchy.

The actress will portray Emma Jean, an expensive escort who shakes things up for the SAMCRO crew in Season 5. She will appear in at least two episodes this season, although it is unclear when she will make her debut on the show.

We reported back in April that Jimmy Smits is also guest starring this season as Latin gangster Nero Padilla, who mentors Charlie Hunnam's Jax. Harold Perrineau (Lost) will also join the cast as a Season 5 guest star.

FX hasn't announced when the Season 5 premiere will air yet, although it will likely debut sometime in September.
