Recording artist Kelly Rowland replaced Minogue last season because the "X Factor" tapings conflicted with those for "Australia's Got Talent" for which Minogue is also a judge.
The BBC reported Rowland recently announced she won't return as a judge next season, sparking rumors Minogue would reclaim her place on the show.
However, an "X Factor" representative told the British broadcaster this isn't true and guest judges are being lined up while producers seek a permanent replacement.
Judges Tulisa Contostavlos, Gary Barlow and Louis Walsh, as well as host Dermot O'Leary will be back next season, the BBC said.
