Brad Paisley turned up as a surprise guest during Demi Lovato's appearance on Good Morning America on Friday (June 17), but they did not perform their new duet, "Without a Fight." Instead, he contributed some scorching guitar licks to "Stone Cold."

Paisley and Lovato also paired up at the 2016 iHeartRadio Music Awards in April to perform "Stone Cold," and on May 20 he brought her out unannounced at a concert in California to treat fans to the live debut of "Without a Fight." The pair have just released a playful video for the song, which has given Paisley the highest first week radio adds of his career.

Paisley backed Lovato capably during her GMA Summer Concert Series performance, showing his instrumental versatility by contributing some bluesy licks to her song. During the show, it was announced that Lovato will return the favor by joining Paisley to perform "Without a Fight" during his scheduled GMA live appearance next Friday (June 24).

The seemingly unlikey pair have just released a playful video for their duet, featuring them goofing off, shoving each other around and sometimes breaking up on camera at their own antics. "Without a Fight" is just one of the interesting partnerships on his upcoming album, which will also feature Mick Jagger, John Fogerty and hip-hop producer Timbaland.

“I wanted the collaborations on this record to be collaborations that took me outside of what you’d typically think and brought that other world into this, but it’s also very country,” Paisley says.

The superstar also performed at Country Jam on Friday night as part of his Life Amplified Tour, bringing his quirky sense of humor, songs and guitar skills to one of the hottest country festivals of the summer for two straight hours of hits.
