Geri: Spice Girls have had anniversary talks

The 43-year-old singer and her former bandmates, Victoria Beckham, Emma Bunton, Mel C and Mel B, have started making plans to do something next year to honour the landmark date but she can't reveal what that might be - yet.

Speaking on 'This Morning', Geri - who was better known as Ginger Spice when in the band - said: "I think it's really faltering that people are still supportive of the Spice Girls individually and collectively, that's beautiful, it's really nice. It almost feels you know that it (the Spice Girls) belongs to everyone, like a generation. So I think it's one of those things that's been discussed, but until it's concrete I wouldn't announce it."

When pushed by hosts Phillip Schofield and Holly Willoughby to give more details on the potential reunion of the Spice Girls - who last performed together at the 2012 London Olympics - she added: "I think it would be nice to celebrate it in some way. I can say that there's been talks! I think that's fair and honest."

Before the Spice Girls do potentially reform for a project in 2016, Geri 

is releasing a new solo album this year - her first since 2005's 'Passion'.

The reason for the 10-year wait between LPs is that Geri wanted to take some time away from the music business to concentrate on raising her daughter Bluebell, who is now nine.

She said: "I wanted to be a mum first and foremost, that's more important I think. But then I thought maybe I could write songs that we can all relate to, I love the creative process, but it's just taken me ages to go through that transition of being that pop star that wears hot pants to grow up a little bit and find that material that really reflects who I am, so I've been working on it for ages.

Geri - who is married to Christian Horner, the Team Principal of the Infiniti Red Bull Racing Formula One team - has promised the album will have "great songs and lyrics" and a classic pop sound.
