Last Thursday, ZAC EFRON appeared on the online special "Earth Day! The Musical" . . . but he didn't look quite like himself. He'd put on some muscle, and that may or may not have had something to do with his face taking on a slightly different shape. Some people compared him to "Handsome Squidward" from "SpongeBob SquarePants".
People are speculating that he had plastic surgery, or maybe Botox and other fillers.
Zac has his share of defenders, who are calling out everyone for commenting on his look.
Someone also pointed out that people were freaking.
