A friend and collaborator of the singer Cassie corroborated the singers claim that her ex, media mogul Sean Diddy Combs, was physically and sexually abusive toward her.

In an open letter to Diddy published in Rolling Stone on Thursday, Grammy-winning singer-songwriter Tiffany Red said he traumatized her. Reds piece follows Cassies lawsuit against Diddy , which was filed on Nov. 16 and privately settled less than 24 hours later.

Im breaking my silence, freeing myself from haunting recollections, standing in solidarity with Cassie, and standing up for myself, Red wrote. I fear for my safety as her suit alludes to me, although not by name. I hope that revealing my identity to the public will afford me some measure of protection.

Red has written songs for Cassie, Jennifer Hudson, Fantasia, Tamar Braxton, Zendaya and more, according to her website .

In the Me and U singers lawsuit, Cassie claimed Diddy repeatedly beat her, raped her and forced her to abuse drugs and alcohol. She also claimed he blew up the car of rapper-producer Kid Cudi when Diddy learned Cudi had a romantic interest in Cassie. Cassie also said Diddy would force her to do Freak Offs, a term he used to describe her having sex with multiple male sex workers as he watched, recorded and pleasured himself.

In her letter, Red said she has memories of numerous instances of Diddy being abusive toward Cassie that have since tormented her. Red also claimed that everything in Cassies lawsuit was consistent with what she witnessed as Cassies friend.

Your abuse of power has inflicted ongoing harm on countless individuals, including myself, my friends, and my peers, she wrote. The power imbalance makes it nearly impossible to fight back and terrifying to speak up. But despite that, here I am, standing beside my friend.
