Cyrus co-stars on The Disney Channel family comedy with his 16-year-old daughter, Miley. The cast recently completed work on the show’s third season.

Cyrus said in an interview for “Access Hollywood” and “The Billy Bush Show” that Season 4 of “Montana” is expected to air in 2010 and to include 11 half-hour installments and a 1-hour series finale.

“Quite frankly, I give a lot of credit to Miley for taking it to another year,” Cyrus said. “She didn’t want it to just end with whatever was the last episode we did. She wanted it to build to where there’s a moral to the story, to where it doesn’t just end and go away and that’s it. She wanted there to be an official ending to ‘Hannah Montana.’”

He said the final season is slated to start shooting around the end of January.

No one was sure whether Cyrus would return to the series that made her a global star, however Cyrus recently expressing her intention to continue her small-screen duties as Miley Stewart/Hannah Montana for another year.

As part of the deal, Cyrus will get a long hiatus to work on the feature “The Last Song,” with production on the fourth season of “Hannah Montana” slated to begin next year. (Filming of the show’s third season wraps this week.)

The series will change settings next season, during which the Stewarts will grapple with saying goodbye to their beachfront Malibu home.

The 16-year-old star of TV character Hannah Montana has vowed she will not have sex before marriage.

Miley is currently dating a 20-year-old underwear model.
