Scotty McCreery Joins Brad Paisley Onstage (But Avoids the Prank Wars) During Tour Finale

One year ago, 'American Idol' winner Scotty McCreery would have had to buy an expensive ticket to see Brad Paisley up close. Sunday night in Raleigh, N.C., the 17-year-old breezed backstage to hang out with the CMA Entertainer of the Year nominee, before joining him onstage.

"Look who's here tonight. Hopefully @ScottyMcCreery is learning how NOT to behave on tour," Paisley tweeted, along with the picture of the two seen above.

McCreery joined the tour's opening acts and local radio personalities to sing 'Alcohol' during the show's closing moments. It was Paisley's final night of the H2O II Tour, and the McCreery cameo wasn't the only surprise. The prank wars were at a fever pitch.

Earlier, opener Sunny Sweeney pranked Paisley by replacing his fishing chair with a throne of a porcelain kind. The 'Drink Myself Single' singer tweeted a picture of the toilet, and Paisley also mentioned it on his Twitter page, proving that he can take the pranks as well as he can dish them. And boy did he dish them.

During Jerrod Niemann's set, popular prankman 'Sweet Pea' appeared in a flashy body suit that left little to the imagination. But Blake Shelton got it the worst. Paisley printed off and distributed over 200 Shelton meet and greets, leaving his entire team overwhelmed before the show. Shelton later retaliated by appearing in a mullet during his duet with Paisley, but that wasn't nearly as good as some of Paisley's shots.

The JaneDear Girls and Eden's Edge were the other openers on the tour.
