Is Shawn Mendes's voice changing?

Shawn Mendes is usually super chill, but lately, he's been going through something so frustrating that he can't help but vent! " My voice needs to figure itself out and stop going through puberty," he tweeted back in May, just as he was kicking off Taylor Swift's 1989 Tour. Months later, the problem is still there! "The day my voice stops changing will be glorious," Shawn recently spoke out. "I'll buy everybody tea." Aww!
