On Monday's episode of The Late Late Show, Shawn Mendes appeared in the latest installment of host James Corden's popular segment "Carpool Karaoke."
During a drive through L.A., the two belted out songs like "There's Nothing Holding Me Back" and "Mercy." But the highlight of the segment came when Mendes revealed that he is a diehard Harry Potter fan.
"On a scale of 10 being crazed superfan and zero is, hate it, never seen it, where are you?" Corden asked. "9.5," Mendes replied.
"I have a whole book at home that I wrote all the spells in and stuff." The camera went on to cut to Mendes wearing a full-on Hogwarts robe and discussing how starstruck and sweaty he was when he met Emma Watson.
He then tried to downplay his love for the Harry potter franchise by explaining, "I'm like a fan, I like it, but I'm not like crazy obsessed with it."
