Camila Cabello mistake a contestant on The Voice for her ex-Shawn Mendes

On the Sept. 27 episode of the hit NBC singing competition show, the Fifth Harmony alum Camila Cabello was shocked after hearing contestant Tanner Howe's vocal abilities during the blind auditions. Why? Because he sounded just like her ex-boyfriend Shawn Mendes while belting out his hit Mercy.

"Is that my—is that Shawn up there?" Cabello asked her fellow coach , appearing for a moment to honestly believe her former flame was auditioning behind her. "I thought that was Shawn."

Following Howe's performance, Cabello congratulated him and admitted, "I was like, 'Is Shawn onstage right now?'"

 Co-judge John Legend agreed, "You sounded like him."

Howe responded to Cabello, "Well, you know him best, so that's awesome," to which she hilariously replied, "I know him better than everybody in this room."

The Havana singer then explained why she was the only one of the four coaches who didn't turn her chair for the contestant. Watch the moment in the video below!
