Demi Lovato [1] stopped by The Tonight Show Starring Jimmy Fallon [2] this week, where she revealed a very fun and interesting fact about her "Sorry Not Sorry" music video [3]. When Jimmy asked her about the inspiration behind the massive house party vibe in the video, she revealed it's actually all thanks to Snoop Dogg. "It was inspired by a house party that I had," she said. "All of a sudden my house is filled with pot smoke, everywhere. I was like, 'No smoking inside, get out, get out.' I wasn't going to tell Snoop not to smoke in my house so I was like, 'OK, Snoop, do whatever you want.'" Good call, Demi.
