Ariana Grande revealed in an interview last month that she was miserable on the set of Victorious because she felt bullied by one of her co-stars.

Thanks to their public feud on Twitter earlier this year, many people assumed that she was talking about Victoria Justice. But Ariana was quick to clear up the rumors, taking to her Tumblr to set the record straight. She explained that she'd been misquoted and a little too vague in her interview.

So why is Ariana now upset, weeks later? According to reports, Victoria's fans showed up at the Sam & Cat star's magazine signing and called her mean names. Security decided that the situation was a safety hazard, and decided to shut down the event early.

Yesterday, Ariana took to Twitter to share her frustration with fans.
