North West, the 12-year-old daughter of Kanye West and Kim Kardashian, performed alongside him in a surprise duet at his concert at Los Angeles' SoFi Stadium on April 1. The duet, "Talking" and "Piercing On My Hand," was a response to critics who have criticized North's fashion and body piercing choices. In the song, North raps about her desire to have more piercings and tats, while Ye wore an all gray ensemble. This isn't the first time North has ignored her critics. Kim Kardashian also expressed her love for North's style and rules regarding other aspects of her kids' lives.
