Tana Mongeau, Dolan Twins & JoJo Siwa Among JJJ's Top Creators of 2019 - See Who Made The List!
3. JoJo Siwa
JoJo embarked on a massive world tour, and at one show, she wiped out, but had the best reaction to the moment. The tour was so successful, she added 50 more dates! There was also a concert special and her birthday special that aired on Nickelodeon. This year, JoJo had some words for trolls who had something to say about her hairline. She ended the year by picking up an honor at the 2019 Streamys Premiere Awards.
