Ginger Spice was the sauciest of the band - here we look at what happened when she left the band, and her family life.
Geri is 46-years-old. She was born on August 6 1972 at Watford General Hospital as Geraldine Estelle Halliwell.
Her dad Laurence - who sadly passed away in 1993 - was of English and Swedish descent, and her mum Ana Maria is Spanish.
Geri was the smallest of the Spice Girls, standing at just 5 feet 1 inch, or 155 cm.
According to Time, Geri has an estimate personal fortune of £30 million - and not all of it came from being in the Spice Girls with Mel B, Emma Bunton, Victoria Beckham and Mel C.
As well as her earnings from the Spice Girls, she also enjoyed a stint judging Australia's Got Talent, has written a series of successful children's books, and enjoyed musical success as a solo artist.
In May 2015 Geri wed Red Bull Racing boss Christian Horner.
They began dating in February 2014, and announced their engagement in November of that year.
Geri welcomed her first child, Blubell Madonna in May 2006, with baby Montague (or Monty) being born in January 2017, two years after marrying his dad Christian.
Geri has spoken about how Bluebell - her child with film director Sacha Gervasi - has relished going from an only child to a big sister, stepsister and stepdaughter.
In 2017 she said: “I never forced anything, I let them [Bluebell and Christian] find their own way.
"She calls him Daddy and that was her choice. They have a really nice bond.
"It has all been a huge change for Bluey, after having me to herself for so long, suddenly having not just Christian in her life, but a little stepsister, who is just so sweet and now a baby brother.
“It's a lot for a young girl but she's a great kid, smart and funny with a big heart. I'm proud of her.”
Geri announced - via her solicitor - that she had quit the Spice Girls on May 31 1998.
It was reported that she decided to leave the band as she was suffering from depression, and because of creative differences within the group.
The Spice Girls carried on as a four piece, but split in 2000. They reformed as a five piece in 2007, embarking on a global tour which they were estimated to have earned £10m each.
