Well I do know she received a lot of bullying for being mixed raced in an all white community in her childhood and often the bullied end up being bullies.
I've actually never heard Victoria speak ill of her. I do know Geri said in her Piers Morgan interview that there were issues between her and Mel B and Melanie C has been quite open about the issues with Mel B being mean to her in the early days. I do remember in Mel B's autobiography she said the book was an official apology to Melanie C and talked about how sometimes she would be mean to Melanie C even though she was the one in the band she wanted to be closest to. I felt like all of that had been water under the bridge though after the reunion tour like we saw Melanie C be her guest judge at Judges houses on X Factor Australia and saw pictures of them partying when Mel B was promoting for once in my life and at the viva forever press launch and premiere while you could see the tension between Mel B and Victoria the two Melanie's seemed quite close and I remember Melanie C talking about texting Mel B when she went into labour with Scarlett because she going to deliver in the same room that Mel B had given birth to Phoenix in.
I had really hoped they were all starting to make amends especially after the death of Melanie's father. It's sad especially with their friendship being such a huge part of their brands.
