JoJo Siwa said Candace Cameron Bure is the rudest celebrity she's ever met. She filmed a TikTok video, where she flashed images of celebrities for different categories. JoJo also said that Zendaya is her celebrity crush, Miley Cyrus is the nicest, and Elton John is the coolest. Oh, and SpongeBob SquarePants did her dirty. She didn't give an explanation for any of them. But SpongeBob was probably in reference to her relationship with Nickelodeon. Remember when she wasn't invited to the Kids' Choice Awards?
