Former Spice Girl band mate, Mel B, has been accused of intimidating a witness, who was prepared to testify against her in her bitter divorce war with Stephen Belafonte, and police have opened a felony investigation.

Rapper Siya, who starred in “Sisterhood of Hip Hop,” filed a police report Monday, claiming Mel B sent her texts last Saturday threatening that if Siya dared testify against her, she would show her another side of her.

TMZ reports that,  Siya showed police the text messages and a felony witness intimidation case was opened.

Siya was prepared to contradict Mel B and testify Belafonte never physically abused his wife.

Siya claims she was a close friend of both Mel B and Belafonte. Sources connected with Mel B dispute that, saying Mel B only met Siya a couple of times. Siya is prepared to testify Mel B frequently used illegal drugs.

She’s also prepared to testify about the 3-ways between Mel B, Belafonte and their nanny, Lorraine Gilles.

Siya claims Mel B was the one who called the shots in the 3-ways.
