Miley Cyrus, Demi Lovato

Two of the Disney Channel's teen queens will continue their reigns: The cabler has ordered new seasons of Hannah Montana and Sonny with a Chance.

Hannah Montana, starring Miley Cyrus, will begin production on Season 4 early next year. Coming off of this season's upcoming cliff-hanger, the next cycle will find the Stewart clan struggling to say goodbye to their Malibu home.

"Hannah Montana has become one of the most iconic series in television history," Disney Channel president Gary Marsh said in announcing the pick-up. "Miley and the producers have proposed a change of setting for Season 4 that will provide the catalyst for wonderful new characters and ... storytelling opportunities."

Sonny with a Chance, starring Demi Lovato, will return for a second season. During its freshman run, it emerged as TV's No.1 -rated scripted series among kids age 6-11 and tweens (nearly tying American Idol in the 9-14 demo).

"Sonny was a hit right out of the gate," said Marsh. "[We] look forward to tapping further into its comedic potential, adding music, and more, in Season 2."
