Earlier this month, a clip of the Hello singer making enthusiastic expressions and gestures ahead of Rihanna's Super Bowl Halftime Show began circulating on social media. And during her concert in Las Vegas on Friday, Adele addressed the popularity of the video. "It's hard work being a constant meme. I don't know what it is about my face but every time I step out of the house, maybe it's because I don't have any Botox or anything, I'm just... my face just moves so much."
