She has allegedly been informed by the show's bosses that she has a "great chance" of replacing either female judge on next year's series.
Mel B is reportedly "getting signs" that she will be able to have a role on the singing show.
The Mirror reports that the 37-year-old Spice Girl, who is currently a judge on the Australian version of the series, has also started looking into schools for her children in London ahead of a permanent relocation.
The newspaper quotes a source as saying that she is "ready to come back" to Britain.
They continued: "All her obligations in Australia, where she's been living for two years, come to completion at the end of January."
Mel B won praise by many for her performance as a temporary judge during the auditions stage of the ITV1 show.
