Washington, Feb 19: Dolly Parton will not make a guest appearance in the latest `Hannah Montana' flick because studio bosses forgot to write her part in the script.

The `Coat of Many Color' hitmaker, who has appeared in many `Hannah Montana' episodes, is disappointed that she was not included in the latest Disney offering.

"I''m not in the movie. I wish I had been. I said I would love to (be in it)! I assumed that they were gonna be writing me a part," Contactmusic quoted Dolly, as saying.

The `Hannah Montana' flick hits cinemas in May (09).

Dolly, who has played Cyrus' aunt in many the hit teen series, is her godmother in real life. (ANI)
