One month ago, 8-year-old Sophia Grace Brownlee was just a little girl singing along to a song by rap princess, Nicki Minaj—but fast forward a mere four weeks and not only is the second grader a worldwide phenomenon, but she is also now Minaj’s friend. After Brownlee’s cover of Minaj’s “Super Bass” racked up more than 13 million hits on YouTube, TV host Ellen DeGeneres invited both Sophia Grace and her 5-year-old co-star and cousin Rosie Grace McClellan to The Ellen Show where Minaj surprised the two tiny princesses and accompanied Brownlee live. The rapper also sent the little girls on a shopping spree to Toys 'R' Us, dispensed some “stay in school” advice—and snapped this backstage photo, which Brownlee posted on Twitter.
