The 37-year-old singer has confirmed that she will be a guest judge during the show's Manchester auditions, reported Sun online.
"I am so, so, so excited to be a guest judge in Manchester. Being a northern girl, I believe there is lots of amazing talent in the north of England. I am coming to find the winner," said Brown who is a regular on the judging panel of the Australian version of the show.
"I love my job as a judge on The X Factor Australia, but it will be great to sit on the panel in the UK. Britain is, and always will be, my home and first love," she said.
Brown will join Gary Barlow, Tulisa and Louis Walsh for three days of auditions from today. Producers are yet to find a permanent fourth judge.
