"It gets quite heated backstage, and quite competitive."
"I don't feel like I'm a competitive person. I feel like the best person should win 'The X Factor', whether they're in my category or not," she said.
"But he's so competitive and so rude sometimes that I find myself getting caught up in it... Honestly, he's really annoying. Really annoying."
