The 'Right There' singer admits she gave the Take That man a slap on the wrist following last week's heated row.
Nicole Scherzinger has hit out at her fellow The X Factor judges and their "pathetic" on screen rows.
The former Pussycat Doll admitted she is the one trying to keep the peace between the panel and was disappointed to see Tulisa and Gary come to blows last weekend.
"I am trying to keep this one, big happy family but it can be hard," she told the Daily Mirror. "When Gary and Tulisa had that pathetic argument last week, it was my job to try to keep the peace."
She also revealed how she told the Take That singer to apologise to the N-Dubz star after comments on her breath.
"After he said her breath smelt, I went up and gave him a slap on the wrists and told him he can’' speak to women like that, so he went and apologised," she added.
Nicole was also questioned about any female rivalry, which has occurred in previous shows with former judges.
The 'Don't Hold Your Breath' star denied anything of the sort, and stated: "Tulisa's a righteous chick and I really like her."
Meanwhile, tonight's (4th November) results show will see live performances from Rita Ora and No Doubt.
