It almost sounds scripted, doesn’t it? Two relatively unknown actors get cast in the leading roles for a Disney TV movie. Wonder of wonders, the movie becomes one of Disney’s biggest hits, spawning a best-selling album, huge ratings, and sequels.

Magazine says it’s all over - Efron ended the relationship at least a week ago. Friends of the stars, however, say they don’t think it’s all really finished for the budding young couple.
