Kelley told IHeartRadio
why he was so enthused to record this song: "I knew I needed something off the record that had a little bit more groove to it," he said. "Because a lot of the songs are a little more introspective and heavy."
"And 'Lonely Girl,' the lyrics are even a little arrogant. It's like, anytime you get lonely, just put this record on, and, I'm right there with you," Kelley continued. "For me, though, this song's all about the groove and the vocal delivery. I wanted to find songs, too, that pulled out a grittier side, and this song definitely did."
