Once upon a time Zac Efron and Vanessa Hudgens are also known as #zanessa were the ultimate Disney channel power couple.

Zac Efron and Vanessa Hudgens met for the first time in 2005 while auditioning for High School Musical. When they met and fell for each other on the set of High School Musical their characters Troy Bolton and Gabriella Montez were seriously couple goals in the movie so when they took their love off the screen.

It was seriously a dream come true the two stars were together for five years before they shocked the world and called it quits in 2010 but why did they split?

Efron and Hudgens make their relationship didn't become public until 2006, but outlets report later that Hudgens and Efron quietly began dating in 2005. During the years, the two were inseparable. They posed together on red carpets and were constantly seen cuddling. However, in 2007, the pair reportedly broke up weeks after vacationing together in Hawaii.

A few months later, Hudgens attended the premiere of 'Hairspray' with Efron, prompting rumors the two were back together. In September 2007, nude photos of Hudgens, who was 18, were released online. At the time, she was still dating Efron who didn’t speak on the scandal. However, Hudgens did.

The actress Vanessa released a statement through her rep saying, ‘I want to apologize to my fans, whose support and trust means the world to me. I am embarrassed over this situation and regret having ever taken these photos. I am thankful for the support of my family and friends.’

In May 2008, while filming the third ‘High School Musical’ film, Hudgens and Efron were seen cuddling at a basketball game. Between 2008-2010, the two were spotted more and more together; seemingly more comfortable with showing their relationship to the world. They were even seen kissing. But in December 2010, the pair broke up. 

There are rumors the relationship ended because Efron wanted to be single and Vanessa admitted to being jealous of the overwhelming attention that Zac received from fans, and long-distance was cited as a source of problems for the couple – just like any other relationship that involves two actors or musicians. However, the real reason why they split is still a point of contention that involves a couple of different sources and reports.

The world fell in love with Vanessa Hudgens and Zac Efron as a pair and, even nearly a decade later, Vanessa still gets asked about the status of her relationship – even if it would now be a friendship – with Zac. However, because Vanessa and Zac have been so private about what actually happened during their relationship and after their breakup, it has been somewhat of a mystery to figure out where the two of them stand.

It's been a decade since they left, but since they remain one of the most iconic couples in Hollywood, fans still hope that Zac Efron and Vanessa Hudgens will meet one day.
