Nicole Scherzingerand former Pussycat Dolls bandmate Kimberly Wyatt are said to have been 'kept apart' backstage at The X Factor on Sunday (2nd December).
The pair reportedly fell out following the end of PCD, with Scherzinger and Wyatt's entourages making sure they did not come into contact with each other after Kimberly was present in the audience for Sunday's results show.

A audience member told The Sun: "It was awkward. When her presence was announced, Nicole swivelled round in her judge's chair, gave Kimberly a cool stare and didn't even wave before turning her back again."
Wyatt and Nicole then both appeared on The Xtra Factor, but featured in different sections of the show.
A insider backstage at the ITV1 talent show added: "They were kept apart. There is no love lost. We've got enough fighting on the show without a catfight as well."
Last week, it was claimed by ex-PCD star Carmit Bachar that[uuid=918796b0-b525-41cc-a1c0-a2ad57edca43] Scherzinger was 'jealous' of Ashley Roberts[/uuid] - who came second on I'm A Celebrity… Get Me Out Of Here! over the weekend - blaming the end of the girlband on Nicole.
