The potential comeback has been rumoured amid talk of feuds within the band.
And one of the most noteworthy supposed bust-ups was between Mel B and Mel C, who were said to have stopped talking at one stage.
An insider previously told The Sun on Sunday: "While Mel B, Geri Horner and Emma Bunton are ploughing ahead, there is no love lost between the Mels, who aren’t on speaking terms and haven’t been for two months."
