OK! magazine is providing us with more details on the Zanessa split! “Zac ended it,” an insider close to the pair reveals exclusively to OK!. And the reason?

For you High School Musical fans, there are rumors that #3 is already in the works. Insiders are saying that as early as October 10th, 2008, we could be getting another serving of the teen phenomenon. According to one source, “They are still working on the script and title, one title being explored is ‘Haunted High School Musical’ as the release is around Halloween, but now some recent interviews deny that and make the plot sound more like ‘prom and graduation.’” Reportedly, Zac Efron, Vanessa Hudgens, Ashley Tisdale, and Corbin Bleu are all signed on to star in HSM 3.
