Last night, ‘The High School Musical’ cast reunited to perform their famous hit song, ‘We’re All in This Together.’

And although Vanessa Hudgens and Zac Efron (who opted not to sing, but instead, introduced his past co-stars) weren’t physically together during the singalong, this is the closest they’ve worked since their famous breakup in 2011.

Which, naturally, has fans curious about what went wrong between the two all those years ago. We’ve got the answers.

Here’s what happened during their almost six-year romance:

In early 2005, Efron and Hudgens met while auditioning for ‘High School Musical.’

During the scene reading, the two were paired together. And their chemistry must’ve been off the charts seeing as they both got the parts.

Although their relationship wasn’t confirmed until 2006, the two officially started dating in 2005 but kept their relationship quiet and away from the public eye.

‘We created a bond right from the start,’ Hudgens toldPeople. ‘We were like, ‘We’re doing this, it’s us or nothing.’

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 a Rolling Stone interview, Efron called Hudgens ‘sexy.’

‘The weird thing that no one expected about Vanessa is that underneath such a sweet girl … is a very sexy woman,’ he said.

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 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.’

Since then, Hudgens has openly discussed the leaked photos. This year she toldCosmopolitan UK, 'It’s really f*cked up that people feel like they are entitled enough to share something that personal with the world.'

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.

However, in January 2011, multiple outlets reported the two were back on as they were seen kissing at a Hollywood event.

But the reconciliation fizzled and in September 2011, Hudgens started dating Austin Butler.
