In November 2021, a tweet containing a mashup of "Water Under the Bridge" and Megan Thee Stallion's performance of "Body" at the American Music Awards of 2020 went viral. A dance challenge with the mashup gained popularity on TikTok and users attempted to recreate the clip's choreography, in spite of Adele's apprehensions about the application. Three months later, Megan stated she had seen the clip and revealed Adele was her dream collaboration: "If Adele wants me to come get on the track, be the dancer, I'm there, I'm here for it." Adele included this choreography while performing the song at her British Summer Time concerts on 1 and 2 July 2022. She added it in the set list of her concert residency Weekends with Adele.
