Meghan Trainor's mom, Kelli, earns a vocal credit on this tune thanks to the inclusion of a phone call between her and her lead-artist daughter. The "All About That Bass" singer explained to OfficialCharts.com how the collaboration happened: "With that session, I wrote and produced the song with my little brother at home. I then took it to this big producer called Johan Carlsson who I love, and I asked him to beef it up. We re-wrote the verses and beefed up the production with real horns, because it's a doo-wop-y song, but we didn't have bridge for it. He suggested we call her up and record her on a big microphone, so I called her and said, 'I really love you mum... tell me how much you love me!', and we recorded her response and cut it up. I've played it to a few people and they just break."

Kelli Trainor was previously shouted out by her daughter on "All About That Bass," in 2014: ("Yeah, my mama she told me, 'Don't worry about your size... She says, 'Boys like a little more booty to hold at night.'")
