Zac Efron Sparks 'Plastic Surgery' Rumours Among Fans After Noticeable 'Change in Appearance'

Zac Efron has got fans questioning whether the former High School Musical heart-throb has undergone plastic surgery, after partaking in a video call on Facebook Watch for Bill Nye's "Earth Day! The Musical."

The 33-year-old former Disney star has been trending all over social media this weekend after fans noticed some drastic "change in appearance".

On Friday, April 23 2021, the popular science educator, Bill Nye, better known as "Bill Nye The Science Guy" teamed up with Facebook Watch, featuring Justin Bieber, Zac Efron and many more, for "Earth Day! The Musical" - a fictional musical which aimed to "harness the creative power of Hollywood and drive awareness to help protect the planet from climate change."

The hilarious 11:45-min-long video goes behind the scenes of the fictional Broadway musical, starring Justin Bieber - as Bill Nye - as he tries to spread awareness of climate change and spur action among young people around the world! In the video clip, Zac said to the camera:

"A big budget musical spectacular? Bill, wow. I knew you were smart, but I think you're a genius."

Unfortunately, fans ended up being too distracted by the change in his jaw and lips to really listen to what The Greatest Showman actor had to say.

Soon screenshots made their way to Twitter, and memes weren't long behind. One particular Twitter user claimed the Baywatch star took inspiration from The Weekends face prosthetics for his “Save Your Tears” music video.

While some of the memes and comments were mean-spirited, other fans genuinely appeared to be surprised but supportive of Zac's seemingly sudden change in appearance, with what appeared to be a more squared out jawline and fullness around his face. One Twitter fan defended the famous actor stating he's "gorgeous no matter what".

Although at this moment there is no confirmation that Zac has gone under the knife, it goes without saying, that no one has the right to make any comment on another's appearance.

As perfectly summoned up by Jameela Jamil in a tweet of her own:

"Risky business piling onto someone about their face or body at the best of times, in particular before even knowing why their appearance has changed. #ZacEfron"

But the well-known fitness fanatic, who in the past has gone through a few body transformations for roles in his career, certainly got fans talking.

This also isn't the first time that Canadian singer, Justin Bieber, has been in the news about his acting skills. Only recently was it reported that he will be cameoing on HBO MAX's Friends: The Reunion special, as "Sputnik", Ross Geller's iconic Halloween costume.
