Every season of The Voice has advisors who are primarily used by coaches during Battle Rounds. In the 18th season, there will four coaches but five advisors.
The mentors for 2020 were announced by the show's Twitter page. "Say hello to our ICONIC Battle Advisor," the page said alongside a photo that featured each of the new advisors and their coaches.
But how can there be an extra advisor? Does one team get two advisors? Well, yeah, but they tend to come as a package deal.
