This year's X Factor audition shows saw a range of guest judges join Gary Barlow, Tulisa and Louis Walsh on the panel, with Anastacia and Mel B both getting plenty of positive reception from viewers.
Despite being named the permanent judge, Nicole barely appeared during the auditions, and didn't seem to connect with viewers when she did.
Mel B's brutal honesty on the other hand won us over, and we would have loved to have seen her as the show's new fourth judge.
It's now been widely reported that X Factor boss Simon Cowell wants Mel B on the show next year, after her commitments to X Factor Australia ruled her out of this year's series.
"He loves the fact that she's upfront and charismatic, and she proved herself as a guest judge at this year's auditions," a source said.
Of course, if Mel does join the panel it means one of the current stars faces the axe, and Nicole is looking the most likely to go.
"Simon's desperate for Mel to sign on the dotted line, he loves how brutally honest she is. If she does [Nicole] will have to face the same failure she did in the US," the source added.
No doubt all this speculation will see Nicole go all out in the live shows to prove to producers that they should keep her!
A spokesperson for The X Factor commented: "No decisions have been made regarding next year's X Factor panel. It's likely these decisions won't be made until the end of the current series at the earliest."
