What happens when Sons of Anarchy meets High School Musical? Viewers of the gritty FX biker drama will find out with the show’s upcoming season.

In the highly unusual casting, Ashley Tisdale (best known as Sharpay Evans from the iconic Disney TV movie High School Musical) will play high-priced escort Emma Jean in a two-episode arc on the upcoming fifth season of Sons of Anarchy. Her character will cause problems for the motorcycle club.

Sons of Anarchy has also cast Billy Brown in a major recurring role for the new season as August Marks, the right-hand man to Harold Perrineau’s gang leader Damon Pope. Brown recently starred on Showtime’s Dexter as the new detective Mike Anderson. He also starred on FX’s short-lived Lights Out as boxer Death Row Reynolds.

Sons of Anarchy season 5 will also feature Dexter‘s Jimmy Smits and Lost‘s Harold Perrineau.
