Kanye West joined his daughter North West at her school dance on Saturday night, where the 6-year-old put on a rap performance for her classmates. The Grammy-winning rapper, 42, has clearly passed down the musical torch to his eldest child, who showed off her dance moves and lyrical talents with an original song. It’s unclear what the title of North’s new track is, however, she name-drops her good friend JoJo Siwa.
