He isn’t even 18 yet, but Scotty McCreery has already won ‘American Idol’ and scored a hit single. Now, he can add a ‘Tonight Show’ appearance to his steadily growing list of accomplishments.

McCreery visited the show on June 15, performing his debut single, ‘I Love You This Big,’ accompanied by a trio of background singers. With the song rising the charts following his ‘Idol’ victory, McCreery is in full-on media blitz mode, and he’s probably approaching the point where he could sing the song in his sleep, but he turned in a rousing performance before an appreciative studio audience.

‘I Love You This Big’ debuted just outside the Top 10 on Billboard’s Hot 100 chart, and has already gone Top 40 at country radio. He’s currently at work on his debut album for Mercury Nashville.
