Rumours of a comeback have been circulating for a number of months now, but earlier today a song appearing to be from three Spice Girls members appeared to have leaked online.

GEM is comprised of Geri Horner (née Halliwell), Emma Bunton and Melanie B and the track in question is called "Song For Her", which can be heard below. Back in July, the trio shared a teaser video and told fans: "You've stood by us for 20 years, and we want to say a big thank you. And we want to celebrate and have a party. And when we do, you're all invited."

Mel B recently told James Corden that two of the Spice Girls simply weren't interested in getting a reunion off the ground: "The other two b**ches didn’t want to do it. No, let me correct that. My other two fellow lovely ladies… Victoria’s busy with her great fashion line, Mel C is doing her own album, and so they graciously said, ‘You three go ahead and do it!’"
