Watch Thomas Rhett's Reaction To Hilarious Prank By Tour Opener Emily Ann Roberts

Emily Ann Roberts planned a hilarious prank on Thomas Rhett to end "The Soundtrack To Life Tour."

Rhett kicked off his tour with a co-headlining show withNiall Horan on July 9 in Nashville, Tennessee. The final concert was slated for Saturday night (October 24) at CHI Health Center in Omaha, Nebraska. Roberts joined Rhett throughout the tour, along with ,Kashus Culpepper, ERNEST, Zach John King, Vincent Mason and Conner Smith on select dates.

Roberts shared a behind-the-scenes look at her end-of-tour prank on Rhett.

"I have been on tour with Thomas Rhett since July. We've had a ball. We've had so much fun," she said in the clip on Instagram. "I have been dressing up in all these different disguises for Operation Ticket Upgrade. And when Thomas saw me the other night in my Ronnie Dunn getup, he said, 'Are you gonna come out and sing "Heads Carolinas" dressed like that?' And I said, 'No.' And he said, 'You have to do it in Omaha.'

"Be careful what you wish for, buddy," Roberts said.

Roberts transformed her look, which included a wig and fake beard, plus Rhett's merch. She brought a blonde wig and her own merch for Rhett to wear during the performance. Rhett immediately laughed when Roberts emerged on stage to duet Jo Dee Messina 's "Heads Carolina, Tails California." Roberts' husband, Chris Sasser, also shared the prank on the Sasser House Instagram account. Watch both clips below.
