They are reportedly releasing the song in July, to mark ten years since their debut, ‘Wannabe’, reached the number one spot in the UK.
The girls are also said to be planning a reunion tour - and may even release more new material if ‘Woman’ is a hit.
A source told Britain’s News of the World newspaper: "They are planning their tour but wanted a new song to mark their return. If it goes well they’ll look to release more material."
