She reportedly had a secret fling with lesbian lovers Christa Parker and Elizabeth Rodriguez, who have spoken out to say they now believe Mel B is in a 'fragile' state of mind.
Christa, a mother of two, alleged that the former 'Spice Girl' singer started a lesbian affair with her after meeting her at the gates of their children's school in America.
She also admitted to introducing Mel to her 26-year-old friend Elizabeth Rodriguez, a sex-toy saleswoman, following which they had three-in-a-bed sessions.
Christa further said her relationship with Mel became sexual in August 2005, while the singer was dating a casting director.
'I had only had sex with a woman once before...but Mel was obviously very experienced with women. She is a great kisser. Mel and I were very good friends. We saw each other almost every day and would have sex at least a couple of times a week,' the Daily Mail quoted Christa, as telling a Sunday newspaper.
The two women broke up with Mel after the singer started dating Hollywood funnyman Eddie Murphy, said Christa.
She also claimed that Mel was in a fragile emotional state, and was worried about her short-lived marriage to film producer Stephen Belafonte two months ago.
'Mel is so vulnerable. I'm very worried about her. I hope she's happy. I just don't want to see her hurt,' she said.
