Melanie Brown has revealed that the Spice Girls members used to "fight like cats and dogs" during its prime.
The 39-year-old singer said that the group's girls were never relying on their sex appeal, instead relied on how different and outrageous they were as they were the girls doing it for the girls, Us Magazine reported.
The 'America's Got Talent' judge added that though everyone in the group "knew this was a platform" to help launch their respective careers, Geri Halliwell's departure was still "bad".
The 'Viva Forever' singer continued that Halliwell left on Brown's birthday without telling anybody, despite they had the American part of their tour still left.
Brown further added that she still remind Halliwell of the time when she left on her birthday.
