Celebrities were called on to make a video statement about environmentalism for Bill Nye's Earth Day special.
The likes of Justin Bieber, TikTok stars Dixie and Charli D'Amelio, Stranger Things' Gaten Matarazzo, Broadway star Idina Menzel, and DJ Steve Aoki were among the A-listers featured in the 12-minute clip that was uploaded late last week.
They all had different messages for the world, however it was Zac Efron's moment that really surprised viewers.
Many people flocked to social media to question whether the actor had had any work done recently.
But there was an outpouring of support for the star, with loads of Twitter users hitting back at the pile on.
Efron recently revealed how he was 'hit in the face' by a rake while filming a new series with Netflix.
The Baywatch star used the oldest gag in Hollywood during shooting scenes for a new episode of his show Down To Earth.
The series sees Efron and wellness expert Darin Olien search for healthy and sustainable ways to live, which is probably why he was in a vegetable garden when he had a close encounter with the rake.
On first glance, the star really does seem to be smashed in the noggin with the gardening tool. He grabbed his face and fell to the ground in a seemingly large amount of pain.
But people have pointed out that the 33-year-old star looks like he purposefully stepped on the rake before throwing his hand up in an effort to stop it actually hitting him.
Though his reaction is well-timed, it seems the rake never actually reaches his face, and that he was simply showing off his acting skills.
