Taylor Swift performed on the show's Season 6 premiere episode this week.
Adkins is slated to perform his No. 1 single "You're Gonna Miss This" with the remaining 11 acts on Monday's live installment.
The finalists are split up into three groups -- female solo artists, male solo artists and groups.
The celebrity judges -- singer-songwriter and producer John Rich; singer-songwriter Jewel; and songwriter Jeffery Steele -- are to be surprised in the next episode when they are each assigned to mentor one of these groups through the rest of the show, NBC said.
