Miley Cyrus has announced she is ending her four-year run as the Disney Channel's 'Hannah Montana' after this season, to focus on other acting opportunities. Already in production, the final episode will feature the return of Dolly Parton, reprising her role as Aunt Dolly.

The superstar, who is also Miley's godmother, is bursting with pride at the choice the teen singer/actress has made. "I'm very proud of her," Dolly tells Knox News. "I think she's a fabulous artist."

Miley won't have to wait long to return the favor. Dolly is working on a TV special which will originate from her theme park, Dollywood, celebrating the 25th anniversary of the popular tourist destination's grand opening. And in addition to Miley, other stars already confirmed to appear include her father Billy Ray Cyrus and Kenny Rogers.

Miley, who once said she would love to work on a country album with Dolly, has since expressed that country music makes her "nervous."
