Kelly Clarkson and Brandon Blackstock appeared on stage together at the final performance of her tour.

Kelly Clarkson’s husband pulled a sweet prank on the singer while she was on stage for the final performance of her “Meaning Of Life” tour.

Fortunately for fans, the singer didn’t notice right away, allowing Blackstock to fake-strum the instrument and laugh behind her back until she finished the song. The star later explained to the crowd that she was “totally surprised” once she got wise to the prank.

Clarkson went backstage before coming out to do her usual “A Minute & A Glass of Wine” segment that gets streamed live to Facebook.

“My husband just totally surprised me playing a faux guitar on ‘Piece By Piece’ and I lost my mind in the tent back there,” Clarkson told her many viewers on social media. “It’s totally fine. Get your crap together.”
