Ashley Tisdale is set to return as 'High School Musical' character Sharpay Evans in a new film.

The actress will return to the Disney channel for the film 'Sharpay's Fabulous Adventure', a spin-off from the original 'High School Musical' franchise. The movie is set to be filmed this summer and will be released next year.

Ashley, 24, is set also be executive producer of the movie, and will be the only returning original member of the 'High School Musical' cast.

The plot will see Sharpay and her dog, Boi, make their way from fictional school East High to Broadway after being spotted by talent scouts, and while she is trying to make her way as a theatre star, she will meet her match in a rival starlet.

Gary Marsh, chief creative officer, of Disney Channels Worldwide, said in a statement: "In Sharpay, Ashley Tisdale brought to life one of the most memorable comedic characters we've seen in years. This movie captures the absolutely perfect next chapter in Sharpay's life, as she tries to cultivate the humanity buried, deep, deep within her - a challenging and hilarious endeavour."

Ashley's last Disney film, 2008's 'High School Musical 3: Senior Year', took more than $250 million at the box office worldwide.

The young actress has since starred in 'Aliens In The Attic' as well as releasing two pop albums, 'Headstrong' in 2007 and 'Guilty Pleasure' in 2009.
