Are Bella and Zendaya Feuding?

For some reason, Bella's Bellarinas and Zendaya's ZSwaggers sometimes fight over twitter over who's better. And then, crazy rumors get started! the thing is, Bella and Zendaya are best friends both on and off the Shake It Up set and hate seeing the negativity. Bella wrote, "When U don't see me and Z together, it's bcuz we want it that way but Z is busting her butt on her tour... she is my family and always will be. no one can stop that and no one will." Bella later tweeted, "To all the bellarinas and swaggers, stay true to each other, just like we do."
