Beyoncé’s daughter, Rumi, breaks sister Blue Ivy’s record, after the 6-year-old’s feature on the ‘Cowboy Carter’ track, ‘Protector,’ makes history. Rumi celebrates becoming the youngest-charting female artist to appear on the Billboard Hot 100. The music milestone was a record previously held by Blue, who was seven years old when she was featured on the song, ‘Brown Skin Girl,’ off ‘The Lion King: The Gift’ album.
