Sound the freaking alarms, because a potential new pairing may be in the works!
Zac Efron's new peroxide blonde hair may have given him some newfound confidence, because homeboy just followed Selena Gomez on Instagram, and in the celebrity world, that's a BIG deal.
Following leads to DMing, which leads to ALL sorts in this big old social media bubble, so naturally, fans are l o s i n g it.
Selena isn't following Zac back, but we're hoping she will soon!
Seeing as we all grew up watching both Zac and Selena on Disney, you can't blame the '90s babies for freaking out over this development.
Zac and Selena have worked together in the past, kind of... Selena played a sorority president in the 2016 comedy sequel Neighbors 2: Sorority Rising, which saw Zac reprise his role of fraternity president.
"She's awesome," he told ET at the time about her. "She's super talented."
Make it happen, universe.
