Is this the start of something new?
Fans have recently noticed that Zac Efron, 35, is now following Vanessa Hudgens, 34, on Instagram again after the pair split over a decade ago.
The former Disney Channel stars have indirectly reconnected after people noticed the crossover on the social media platform and let's just say they weren't holding back when it came to expressing their reactions to it.
"Zac Efron followed Vanessa Hudgens... just fell to my knees," one user tweeted.
Another referenced an iconic line from High School Musical 2, in which the pair starred together in.
"T as I’m Troy? Not T as in TODAY ZAC EFRON FOLLOWED VANESSA HUDGENS ON INSTAGRAM."
"Zac Efron followed Vanessa Hudgens makes my childhood heart the happiest!" a third chimed in.
"ZAC EFRON FOLLOWED VANESSA HUDGENS ON INSTAGRAM! My #Zanessa heart. Lol what the f*** is happening?!"
Some fans believed that this could be a little teaser to the rumors currently swirling around about both Efron and Hudgens appearing on an upcoming episode of High School Musical: The Musical: The Series, which stars former members of the original cast including Corbin Bleu, Monique Coleman and Lucas Grabeel.
Efron and Hudgens gained fame after the pair starred in Disney Channel's blockbuster movie series, High School Musical. Efron played the role of Troy Bolton, a basketball hunk with dreamy eyes and a lowkey talent as a singer and Hudgens played Gabriella Montez, an A* student who has an overwhelming love for music (and Tory obvs).

The duo's love went way beyond the movies though, as the pair ended up embarking on a five-year romance that eventually came to an end in 2010 and since then, we've seen limited interactions from the two - until now.

Efron went on to continue his career in the world of acting but has recently slowed down to also make time for his other hobbies, including being at one with nature and producing documentaries.
In terms of relationships, the 17 Again actor has been linked with several potentials, though most of the details were kept well under wraps - except for the fact that this man seems to really enjoy satisfying his girlfriends.
Big yikes.
Anyway, as for Hudgens, she also continued in the world of acting going on to star in The Princess Switch and Tick, Tick Boom!
As for her love life, the 34-year-old was liked to Austin Butler for almost a decade before calling it quits with him and settling down with her current fiancé, professional baseballer, Cole Tucker.
So while the two may not be re-kindling their old flame, we're convinced that there's something going on... And we can't wait to find out what it is!
