X Factor judge Tulisa is said to be annoyed at always being compared to new judge Nicole Scherzinger.
Sources close to the N-Dubz star have claimed that she's getting a bit frustrated with the constant questions about the duo's style war and reports of backstage bitching
"Tulisa has no problem with Nicole," says a source, "But she is sick and tired of constantly being played against her - after all, they are vastly different women, with different styles, tastes and opinions.
Speaking to star magazine, the source suggested that Tulisa was annoyed at the "silly competition" set between the girls.
"Tulisa just doesn't get why it has to b a big deal. It shouldn't be some silly competition," the insider added.
Speaking about Nicole and Tulisa recently, [tag]Louis Walsh[/tag] revealed they had been getting on brilliantly.
In an interview with the official website, the show's only remaining judge said: "Tulisa and Nicole are getting on better than any other female Judges have done in the past. No catfights as of yet!
"It’s a walk in the park compared to the year when Sharon and Dannii were Judges. Those two really didn’t get on. It was like a battle of the divas!"
