When news of the upcoming “High School Musical” spin-off “Sharpay’s Fabulous Adventure” first broke, it seemed like a cruel April Fool’s Joke on fans of the bubbly, blonde character (it was announced last April 1st). But it’s official, Ashley Tisdale is in the pink again and reprising her role as Sharpay Evans.

Production has already begun on the upcoming Disney Channel original movie, set to air sometime in 2011. Tisdale will star and executive produce in the movie, which features a Broadway-bound Sharpay hitting the Great White Way to achieve her dreams of stardom. But the doors are opening for her dog Boi instead and Sharpay sets out to make him the biggest little star on Broadway yet.

Also starring alongside Tisdale is Disney Channel star Bradley Steven Perry as her young nemesis, Austin Butler as a film student she befriends, Cameron Goodman as a Broadway star, Alec Mapa as the show’s eccentric director, and Jack Plotnick as the show’s scribe.

The movie is also set to feature four original songs: “I’m Gonna Shine,” “My Boy and Me,” “The Rest of My Life,” and “New York’s Best Kept Secret.” The movie is directed by Michael Lembeck, who recently helmed “Tooth Fairy” for Disney starring Dwayne “The Rock” Johnson, and written by Robert Horn.

The “High School Musical” spin-off is the franchise’s first since “High School Musical 3″ hit theaters in 2008. While rumors are abound that another Wildcat will be making an appearance, such as Lucas Grabeel who played Sharpay’s brother Ryan Evans, nothing has been confirmed.

Tisdale has kept herself busy following her last big-screen appearance as Sharpay. Last summer she released her second album “Guilty Pleasure,” which was voted one of the best albums of last year by Billboard readers, and starred in “Aliens in the Attic.” She’ll also star in the upcoming cheerleading dramedy “Hellcats” for the CW.
