Zac Efron, Vanessa Hudgens Reunion In ‘High School Musical 4’ Threatens Austin Butler?

Zac Efron and Vanessa Hudgens are believed to reunite in front of the cameras after a long time for the next installment of the popular Disney movie, "High School Musical 4." While many fans are excited to see Troy and Gabriella together after so many years, a recent report claims that Hudgens' boyfriend, Austin Butler is not exactly thrilled to hear of their upcoming reunion.

The most awaited reunion between Vanessa Hudgens and Zac Efron is believed to happen in "High School Musical 4" after Disney announced that a sequel to the popular franchise was in the works. This made a lot of fans thrilled since it has been 8 years since they aired "High School Musical 3: Senior Year."

While it would definitely be interesting to see "Zanessa" back together, a report from OK! Magazine suggests that the said reunion between the former couple for "HSM 4" is making Hudgens' boyfriend, Austin Butler, worried. An insider told the publication that the 28-year-old actor continues to call Hudgens every now and then.

Butler allegedly does not trust the "Baywatch" actor and his intentions towards Hudgens. Butler reportedly is aware of the fact that Efron is and "will always be her first love," which intimidates Hudgens' boyfriend.

However, it looks like Butler will not have anything to be intimidated about. A report from Hollywood Life suggests that Efron and Taylor Swift are rumored to be dating each other.

While Efron and Swift have yet to comment on the dating rumors, an insider told the publication that the "Dirty Grandpa" actor is interested in dating the "Blank Space" singer. According to their source, Efron finds Swift "sexy" and is looking into calling her and asking her out once he finds time in his busy schedule.
