In an "Ask Kelly Anything" video published on June 12 onThe Kelly Clarkson Show's YouTube channel, someone asked the daytime talk show host, 43, which song took her the shortest amount of time to write. "A Christmas song. It was'Underneath the Tree.'I was working withGreg Kurstinin the studio," Clarkson said of the music producer who helped her make her 2012 hit"Stronger (What Doesn't Kill You)"and other hits. "I ordered sushi and when it arrived I had written it," the three-time Grammy winner continued. "I think because I really love Christmas I write them really quickly for Christmas — because they feel good, because you can be a little cheesy, you know? You don't have to worry about being cool, which honestly that's not a concern generally ever because I'm not." "Underneath the Tree" was a huge hit for Clarkson, peaking at No. 9on theBillboard' Hot 100 singles chart. It toppedBillboard's Adult Contemporary chart, holding the pinnacle position for four weeks. Elaborating on how the holiday hit came to be, Clarkson said on her show that Kurstin, 56, "sent me home with a little piano thing and we kind of started, not the idea of it, but just kind of the wall of sound for Christmas." She added that "it's a really cool sound at Christmas. It feels nostalgic." "They don't all come out like that, though; usually it takes forever," Clarkson admitted of her songwriting process. "But that one was quick." The PEOPLE Appis now available in the Apple App Store! Download it now for the most binge-worthy celeb content, exclusive video clips, astrology updates and more!
