"It's really cool," Miranda said on set. "Just the vibe out here is sort of a perfect setting for this song in particular."

Even though she's seen singing with a shirtless pool boy in the video, it's Miranda's body that captures the most attention. She heats up the screen in red cowboy boots and Daisy Dukes after losing a reported 45 pounds a year ago.

"Someone told me about the song," Miranda said. "A girl named Audra Mae wrote it. I kind of tracked her down a little bit in a stalker way because I was obsessed with her music and met her and we became friends. I asked her if I could record her song and she said, 'Absolutely!' and she actually sang background on the record."

Miranda shot the music video just three days before her fiery GRAMMY performance in February and last week she surprised fans by inviting her husband Blake Shelton to join her on stage for an impromptu duet during a concert in Oklahoma City. The couple sang Shelton's hit "God Gave Me You."

"I was excited to be here tonight anyway, just to watch my wife Miranda do this awesome show. This has been incredible," Shelton, who was raised in Ada, Okla., told the crowd. "And she asked me if I would come out here and sing a song ... I'm thrilled to do that. But I wanted to do this song tonight because Miranda is the reason I recorded this song."
