Ever since High School Musical 4 was announced to be made, fans have been thinking about the franchise's most beloved faces i.e. Zac Efron and Vanessa Hudgens. Everyone wants them to return and looks like they are not just returning but also reuniting in real life.

Ex-couple Zac Efron and Vanessa Hudgens might be back with each other in real life as well because of High School Musical 4, reports Jobs & Hire. It is said that they are rekindling their romance and since they are back for the fourth installment of the Disney movie that made them stars, it has become easier for them. Notably, rumors of their reunion have been the subject of gossip right from the time the movie began making noise.

They gained momentum when Efron posted an old picture of High School Musical featuring Hudgens and other cast members. He captioned it with a sweet message saying that he was grateful to have found that throwback photo. The actor also said that being in the movie was one of the exciting times of his life and he will forever cherish the moments he spent with the cast members.

In related news, it is rumored that the relationship of Vanessa Hudgens and her current boyfriend Austin Butler is not going steady, reports iTech Post. The couple is said to be on rocky terms and the latter is not happy with the fact that his girlfriend has said yes to the project and will be reprising her famous role. He is allegedly insecure of Efron and feels that working with him might lead to Hudgens calling off their relationship.

His insecurity is so high that he prevents her from talking to Efron off-screen. As for Hudgens, she is miffed with his attitude and the interference is not going down well with her. She has demanded some space from Butler as she wants to focus on her career. What has made all these rumors relevant is the fact that neither of the two has confirmed or denied them.

It may be mentioned here that an official announcement regarding Zac Efron and Vanessa Hudgens' involvement in High School Musical 4 is still awaited.
