"Gaten of #StrangerThings has an awesome voice," Kelly Clarkson declares.
The "Stranger Things" star swung by in a golf cart to pick up Clarkson on her way to host and perform at WE Day Toronto 2017, an event raising money for children's charities that will air on CTV tonight at 7 p.m. EST.
"I'm excited -- I'm terrified, I'm really nervous," she admitted as she climbed in, to which Matarazzo replied, "Don't be, you got this!"
He joined her in some quick vocal warmups, riffing on the word "we," before launching into a cappella versions of Sister Sledge's "We Are Family" and Queen's "We Are the Champions."
By the end of it, we're not sure which star has the better voice. It sounds like the rising child star has at least one hit record in his future.
Clarkson even praised his singing skills in an Instagram post promoting the event.
