Disney has announced plans to make High School Musical 4. The third movie in the franchise is currently being filmed and bosses reckon teen fans will be queuing to see another installment. But stars Vanessa Hudgens, 19, and Zac Efron, 20, may not be returning.

“We have to have a new story,” Rich Ross of Disney Channel Worldwide tells the Daily Star. “Will we have all the cast back? Probably not, but we hope to have some [of them].”
