Ahead of the two artists' upcoming collaboration, they came together for a fun social media video on Sept. 18, with the "Espresso" singer, 25, joking that the Grammy winner, 43, is her "mom." In the video, the pair sits on a couch with a full band behind them as Carpenter lip-syncs to a sound of Kylie Jenner — who's dressed as Aguilera for Halloween in the past — speaking about her mother, Kris. "I'm obsessed with my mom," says the makeup mogul. "So you're saying you're her favorite?" someone else asks in the audio, while Carpenter pans the camera to show Aguilera. "That's exactly what I'm saying," continues the clip of Jenner, while both singers smile and laugh. "I'm her favorite. We actually have a relationship like she has no other kids. Yeah." Aguilera shared the video alongside the caption, "Obsessed."
