Sophia Grace, who was nine at the time, and her then five-year-old cousin Rosie caught the attention of Ellen DeGeneres after a video of them dancing to Nikki Minaj's Super Bass went viral.
The pair were then invited to perform the song on Ellen's eponymous show.
Sophia Grace and Rosie captured hearts worldwide as they performed the number on the Ellen DeGeneres Show wearing pink tutus in the US, with Sophia Grace blowing viewers away by showing off her rapping skills.
Following the TV appearance, Sophia and Rosie became overnight sensations and were repeatedly invited back on Ellen's show.
Ellen even invited the duo on red carpet trips to interview celebs they were big fans of including Justin Bieber and Drake.
They made their last appearance on the show earlier this year to say goodbye to the talkshow on its final series.
Sophia Grace and Rosie performed Super Bass for the final time to bid farewell to The Ellen Show, which wrapped for the final time in May this year.
