It's one of the hazards of riding a bike! Justin Bieber had some serious helmet head after tooling around on his custom Drew House motocross bike, on Wednesday.

The singer jumped in his Range Rover with wife Hailey Baldwin after a quick joy ride and they headed to TWO dermatologist appointments! We can only imagine Justin's getting acne treatment for his pretty severe outbreak. But hey, he told us pimples are cool and we're starting to believe him! Emma Chamberlain shows hers off, Billie Eilish ... I mean, acne's on-trend!
