Vanessa Hudgens, Austin Butler Breakup: Zac Efron Keeps Calling Ex-Girlfriend?

Zac Efron and Vanessa Hudgens are expected to be reuniting for "High School Musical 4" and this is making Hudgens' boyfriend, Austin Butler worried. A recent report claims that Butler's worries are without a cause, as Efron is reportedly still not over and is still in touch with his ex-girlfriend.

Vanessa Hudgens and Zac Efron reunion rumors are currently making rounds online after Disney announced the release of the sequel to their hit movie franchise, "High School Musical 4." While it remains to be seen whether Zanessa will be reuniting for the big screens, this impending reunion is allegedly making Austin Butler worried.

According to OK! Magazine, Butler does not trust Efron because he continues to call Hudgens even though they did not end in good terms. The insider claims that the "Baywatch" actor is still not over his ex-girlfriend and is still looking for a chance to work things out because he has and "will always be her first love."

As most fans can recall, Hudgens and Efron met and began dating on the set of "HSM." The couple was together for years before announcing their breakup in 2010. Since then, Hudgens dated Butler while Efron dated several ladies.

It looks like Austin Butler does not have anything to worry about, though, as "HSM 4" will reportedly not feature any of the original cast members of the Disney movie. This means that neither Hudgens nor Efron will be reprising their roles in the upcoming sequel.

Meanwhile, the "Dirty Grandpa" remains the top choice among fans and even actresses nowadays. According to Us Weekly, "Scream Queens" actress Lea Michele recently played a game of "Who'd You Rather?" with Ellen DeGeneres.

Michele was asked to choose from a list of hot actors and famous people, including Tom Hiddleston, Calvin Harris, Michael Jordan and Zac Efron. The "Glee" actress finally ended up choosing Efron as her ultimate crush.
