• This bluesy, boozy barroom romp finds Lambert addressing the difficulties of getting older and her struggles with weight. The Nashville star told US Weekly that she thinks expressing herself authentically through music is imperative to her listeners. "My fans expect me to lay it all out!" Lambert said. "I've always been happy with myself. But when I hit 30, I thought, It's not going to get easier. So I chose to get ahead of it. There's still nothing I love more than a bag of Cheetos, though!"
• Lambert told Billboard magazine the story of the song: "I wrote this with my guitar player Scotty Wray, he's been with me since I was 17, he's in his 50s," she explained. "We came to me at a festival and said, 'hey, I got a title: Gravity's A Bitch.' I said, 'yes it is. Let's write it.' So we got in the bus and literally wrote it in like 30 minutes, it kind of wrote itself."
  
  "He has these amazing melodies, he plays guitar so well, and I said, 'I know what it's like after 30, you tell me the rest, what do I have to look forward to?' We just started writing little things about every age," Lambert continued. "It was fun, it's one of those things you have to face, everybody knows it's gonna happen. That's why there's Botox and Spanx, I guess."
