Zac Efron is once again raising eyebrows about his appearance after being spotted on set of his new movie Famous on Monday.

At 37, the actor who once charmed us as the fresh-faced star of High School Musical now sports a noticeably different look, with a wider jaw and more angular facial features that have sparked a fresh round of cosmetic surgery rumors.  

While filming the A24 thriller in Los Angeles, Zac kept a low profile in sunglasses, a brown dress shirt, and dark trousers, giving off major 90s era vibes.

The star — who plays dual roles in the movie based on the novel of the same name, including a Hollywood heartthrob and a fan — held paperwork in his hands as he made his way across a parking lot.  

This isn’t the first time Zac has caused a stir over his appearance. 

In 2022, The Baywatch star revealed a dramatic new look, attributing it to a serious fall in 2013 that allegedly ‘shattered his jaw.’

He’s maintained that his changing features are a result of that near-death experience, when a slip in a puddle left his chin bone ‘hanging off his face.’

Despite his explanation, fans continued to question Zac’s transformation after watching Netflix’s A Family Affair over the summer – as well as some behind-the-scenes footage the actor shared on his Instagram account. 

‘What happened to Zac Efron’s face? Did he get a bunch of filler? He looks 50 years up close,’ wrote one.

Yet another added: ‘Can’t be the only one who thinks Zac Efron looks weird with that face … couldn’t concentrate on the movie ……

Others rushed to defend the star, citing his previous surgery following a serious fall years ago. 

‘A tweet about Zac Efron’s face goes viral literally every month & every single time someone has to explain what happened to his jaw & how he had to get reconstructive surgery & what not, this sh** is tiring.’

In November, fans were left surprised at his unrecognizable face in an interview he did for Entertainment Weekly.

The actor was doing a promotional interview with the magazine for his film The Iron Claw at the time.

‘What happened to his face??’ one fan wrote, while another called his face ‘huge.’ 

Zac (seen left in 2007 and right in a behind the scenes clip from A Family Affair) opened up in 2022 about his changing appearance, blaming it on a severe fall that ‘shattered his jaw’ 

Others compared him to characters like Thanos in Avengers and even went as far as naming Prince Farquaad from Shrek.

Other fans reminded everyone of his previous shattered jaw. 

In 2022, Zac appeared on the cover of Men’s Health Magazine, and explained what happened to his face – after rumors of plastic surgery circulated since the prior year.

In his interview, Zac revealed that he had a nasty accident at home that caused the massive transformation in his face.

The star recalled how he slipped on a pair of socks while running at his home – causing him to smash his chin into a granite fountain. 

Zac said that when he was injured, the masseter muscles on the inside of his face and jaw then ‘compensated’ for his injury causing them to grow in size – hence his remarkable transformation.

Their questions: Fans appeared shocked at his appeared in the new interview, which dropped on Monday

He says this explains why he looked so different at the time. ‘The masseters just grew. They just got really, really big.’ 

The High School Musical star also claimed to not know that he was a huge talking point on social media and had in fact gone viral for his different-looking jaw, until his mother called to ask if he had gone under the knife. 

‘If I valued what other people thought of me to the extent that they may think I do,’ he told the magazine, ‘I definitely wouldn’t be able to do this work.’ 

In April 2021, Efron started trending on Twitter after he was seen on a video for Earth Day! The Musical displaying a more prominent square chin and heavier jawline. 

In the clip, Efron eagerly called Bill Nye a ‘genius’ after hearing that he and Justin Bieber were working on a fictional Earth Day musical. 

It led fans to speculate that the handsome star had sought plastic surgery.

Efron’s pal Kyle Sandilands had also spoke on his behalf – saying the Baywatch star would never do such a thing, comparing him to an oil painting by one of the Old Masters.

The Australian radio host, who has known Zac for years, shut down speculation during The Kyle and Jackie O Show at the time.

‘I would know if he’d had any plastic surgery,’ Kyle declared, before telling his co-host Jackie ‘O’ Henderson that ‘of course’ Zac hadn’t had work done.

He then said it would be pointless for the High School Musical heart-throb to have surgery because he’s already so good looking.

‘It’s like getting a Picasso and having a kid finger paint all over it. Why bother?’ he said bluntly.
