Scotty McCreery showed his loyalty to country music once again on tonight's 'American Idol' competition, with a heartfelt performance of John Michael Montgomery's 'Letters From Home.'

McCreery sat perched on a stool, flirting with the audience through his eyes and words -- like a true country star -- as he belted out the Montgomery hit, which received a standing ovation from the crowd.

'Idol' judge Jennifer Lopez said it best when she told the young country hopeful, "There are just some people who are born to do something -- you're born to sing country music," adding, "God blessed you with that. Don't ever forget it."

Aerosmith rocker Steven Tyler called his performance "beautiful" and told McCreery, "I don't think you could have picked a better song to represent who you are, and what you are, and the love you have for singing."

Randy dubbed the 'Idol' contestant a "throwback country guy," and said he admired that McCreery sticks to his guns and doesn't trying to make the crossover into pop music.

McCreery, who was at a loss for words, said he's been an 'American Idol' fan for nine years, so to be on the stage is "like a dream." If he's chosen as one of the top five male singers from tonight's show, he'll sing on the show again on Thursday night.
