Danielle Brown is sticking up for her big sister, Mel B.
In court papers obtained by ET, Mel B, whose real name is Melanie Brown, claimed she was in "fear of her safety" and that of her children -- 5-year-old Madison, whom she shares with Belafonte, as well as her two daughters from previous relationships, Phoenix and Angel.
On Thursday, Mel B's younger sister took to social media to share her thoughts on the allegations.
"Dear all media I won't be selling a story on my sister never have and never will!! Here is my comment below so you can now leave me and my mum alone and let us be united and grieve the loss of my dad," Danielle began her Instagram post
"@stephenthinks11 8 years of abusive calls me and my mum have had stating we would never see Melanie again," she continued. "I am laughing and celebrating as you were wrong.you are a sorry excuse of a man !! To the left to the left everything you own in the box to the left ."
On Wednesday, Belafonte's lawyers told ET their client is "confident that the truth will come out," and requested privacy for both him and his children during this "challenging time."
"What matters most to Mr. Belafonte is the safety and well-being of his daughters and step-daughters," Belafonte's lawyers told ET in a statement. "It's a shame that Ms. Brown elected not to proceed in a respectful and amicable fashion in this very private matter. In due course, Mr. Belafonte will be filing his response to the outrageous and unfounded allegations made by Ms. Brown, which allegations he vehemently denies."
A source close to the former Spice Girl told ET that members of her inner circle are happy about the split
, and claimed that Belafonte "controlled Mel's life."
"Thank God she got away," the source said. "Mel's friends are shocked that it took her this long to finally leave him, but are so relieved that it happened. Everyone is so proud that she finally had the courage to leave him."
"Mel never told friends just how bad the abuse was but everyone knew how scared of him she really was," the source claimed.
