Geri's Back In Spice School

Geri Halliwell’s compared the Spice Girls' reunion to looking back on your school days.

She says it’s a bit like friends who were now a little older and wiser getting back together and realising school was better than they remembered.

Geri’s told GMTV: "It is different. The only way I can describe it is like when you look back on your school days. When you are at school, sometimes you think 'Oh God' but you look back and think actually, that was so much fun, it was a laugh with your schoolmates.”

"It's getting to revisit something, a little bit older, a little bit wiser."

She also let some details about the girls’ comeback single slip out - it’s going to be a ballad called Headlines.

Geri said: "Emma and I initially worked on it with the original writers we used to collaborate with and then the other girls chipped in later on, adding lyrics.”

"Its a Spice Girl classic. We are so proud of it. We started putting words down before we even had the finalised yes from everyone.

"It was kind of like a prayer - when you kind of put the footwork in hoping that it will happen - so it is a really special song, it's kind of magical... It's a big love song."

Talking about tickets for this London shows selling out in 38 seconds, the 35-year-old mum said: "It is kind of shocking. 38 seconds, it's pretty amazing. I cannot quite believe it."

The new Spice Girls album is out on November 12 and the single will be released a week later.
