Geri Horner is keen on a reunion and the singer previously admitted that it was "immature" of her to quit the Spice Girls in 1998.
The British star shocked fans when she decided to leave the band midway through their ‘Spiceworld’ European tour, but claims she felt she had no choice because she could no longer communicate with her bandmates.
She explained: "It was like, ‘You’re getting on my nerves and I don’t know how to talk this through, so I’m out of here.’ It was quite immature, looking back."
