'High School Musical'

High School Musical star Zac Efron has undergone emergency surgery to remove his appendix.

The actor was given an appendectomy yesterday after being rushed to Cedars-Sinai Medical Centre in Los Angeles.

His spokeswoman Gina Hoffman said: "Zac had his appendix removed and is recuperating."

Disney announced on Monday that Efron and co-star Vanessa Hudgens have signed to appear in High School Musical 3: Senior Year, the third installment of the hit franchise.

The 20-year-old recently admitted that he is baffled by the media's interest in his personal life.
