"As a person that loves music -- when did you have to be good looking to be a good singer?" Johns, 30, tells Us. "It doesn't matter what you look like. Idol's proven it doesn't matter what you look like. If you can sing, America will vote for you. Susan Boyle is a good story, I like that."

Johns -- who was a Season Seven finalist on the Fox reality show -- performed his new single, "Heart on My Sleeve," on Idol last week and served as a mentor to the current contestants.

"That was really fun, but you always feel a little unsure, you know what I mean?" he says, adding that he'll be on the season finale as well. "It's weird, my stomach starts churning and everything. I don't know. I love it. It's a great family, and they've been so good to me."
