The former Spice Girl, who is a judge on the Australian version of the reality television series, only has 15-year-old wannabe singer Christina Parie remaining after Jacqui Newland was eliminated in last week's live show, a week after Tyla Bertolli was asked to leave.
Mel B told the Herald Sun: "It's so much fun looking after individuals and not having to think about the group factor. I have a great talent to work with... and we're a great team."

Judges Ronan Keating and Guy Sebastian still have all three of their acts remaining in the contest, while Natalie Bassingthwaighte has two after Cleo Howman was eliminated.
After Newland's departure, all the judges praised her for her "strength" and "courage" to face elimination every week.
Bertolli said that it "sucked" when Mel B was forced to choose between her and Newland two weeks ago and decided to save her rival instead of her.
