Cassadee Pope's time opening Maren Morris' Girl: The World Tour has come to an end, but she went out with a bang, pulling a hilarious prank on her headliner friend before saying her goodbyes.

The prank went down on Pope's last date of the tour, in Los Angeles on March 30. Pope asked Morris' merchandise manager, "Matty Merch," to be her stand-in when it was time do a duet with Morris, and the "Girl" singer's face was ... well, she was shocked.

Each night on the tour, Pope had the responsibility of singing Brothers Osborne's part on their collab with Morris, "All My Favorite People." Matty Merch stepped up to the plate for the big joke, putting on a blonde wig, skirt and even a belly-baring crop top to make himself look as much like The Voice star as possible.

To make him even more her twin, Pope trimmed the merch guy's wig, angling his 'hair' just so.

Instead of Pope, Matty Merch popped up from the back of the stage, mouthing the words to the song as Pope sang from backstage. Morris' face said it all! After a moment of just the lookalike on stage, the real Pope joined them to sing, wearing a matching mini-skirt and Morris T-shirt.

The video clip — seen above in two parts — ends with a message to Pope to Morris:

"Maren, You are one of my favorite people. Thank you for the many memories on tour this past month. Love ya girl, Cassadee."

Pope will be headlining the CMT Next Women of Country Tour which kicks off in Tampa, Fla. on April 11, while Morris will continue on her Girl: The World Tour through the fall.
