OK! Exclusive: Zac Efron Skipped The ‘High School Musical’ Reunion Because Of His Hatred Towards Ex Vanessa Hudgens

Apparently Zac Efron and Vanessa Hudgens still aren’t in this together? Years following their very public break-up, former co-stars turned lovebirds turned exes still are not on good-terms!

A source exclusively told OKMagazine.com that “Zac is creating a huge road block right now because of his resentment towards Vanessa Hudgens.” The source explained that he didn’t attend the reunion because “he wants nothing to do with her.” Back in January, the entire cast, except for Zac, celebrated the exciting 10-year anniversary.

"They did not have a good break up and Vanessa really f—ed him over. He believes that she cheated on him." The source even described Vanessa as a 'sexual nympho'.

Even though both Vanessa and Zac have moved on with their love lives and are in steady relationships with different partners, there's still a lot of problems! The source revealed that “Zac was going to do another HSM originally if the right money was thrown at him,” however the possibility of that happening is “slim now.”

Zac and Vanessa dated for 4 years after they met on the Disney Channel movie High School Musical.
