Zac Efron has finally addressed the rumours of him having plastic surgery last year.
The star, 34, shocked fans when he appeared in an Earth Day! The Musical where he appeared to have a more squared jawline.
Fans immediately took to social media to question whether he had any work done on his face.
Speaking to Men's Health for the October 2022 cover story, he explained he actually shattered his jaw while running in his house with socks on.
The actor had slipped and hit the corner of a fountain before passing out.
He said his 'chin bone' was 'hanging off' his face.
While recovering from the injury, his facial muscles got 'really big' so he teamed up with a physical therapist to help with it.
"The masseters just grew," he said. "They just got really, really big."
The masseter is the muscle in your face and jaw and is one of the primary muscles of chewing.
However, Zac wasn't bothered by the rumours.
"If I valued what other people thought of me to the extent that they may think I do, I definitely wouldn’t be able to do this work," he added to the publication.
After fans noticed the change to his face, they took to social media to worry about it.
“I refuse to believe this is Zac Efron,” one wrote.
“I woke up and zac efron got botched wtf im so devastated,” another said.
An emotional third fan wrote: "I just found out about this and I am literally crying, there are actual tears coming out of my eyes please tell me it's all just a nightmare please zac efron has been the my whole life."

When rumours were circulating about plastic surgery, his pal Kyle Sandilands shut it down during an interview.
"It’s like getting a Picasso and having a kid finger paint all over it," he said on The Kyle and Jackie O radio show.
"Why bother? … I would know if he’d had any plastic surgery."
Zac isn't new to internet rumours as fans recently speculated that he got secretly married after fans noticed him wearing a 'wedding ring' in a video from June.
The High School Musical alum was seen wearing a plaid shirt, a pair of jeans and a jacket in the video, as he talked through various subjects whilst sitting on a bench near the animal.
And a number of his followers said they noticed that he was also sporting a 'wedding ring' in the clip, but none of it was confirmed.
