Country star Brad Paisley loves to pull practical jokes on his tourmates, which means that 'American Idol' champ Scotty McCreery, who's hitting the road with Paisley in 2012, had better be ready.

"I've got to keep my eyes open, 'cause he is a huge practical joker," McCreery tells Billboard. "I have to make sure I don't get pranked too bad." In addition to watching his back, McCreery promises to fight back with pranks of his own. "Well ... I've got a couple in my back pocket," he says. "I've got to think of something good, 'cause he's very unique with his."

McCreery and the Band Perry will be the opening acts on Paisley's tour, which kicks off Jan. 12 in Grand Rapids, Michigan. The teen singer says the tour means a lot to him because he's been a Paisley fan for years.

"It's just going to be incredible," McCreery says. "I've grown up listening to Brad, loving his music. I can probably sing every single one of the words to his songs. It's gonna be fun, and a learning experience for me. It's gonna be a great time."

McCreery will be supporting his debut album, 'Clear As Day,' which hit No. 1 and has produced the hits 'I Love You This Big' and 'The Trouble With Girls.'
