Casandra “Cassie” Ventura is expected to take the stand in her ex Sean “Diddy” Combs Manhattan sex-trafficking trial on Tuesday, with testimony that’s poised to be a tell-all accounting of his alleged pattern of abuse. Here’s what to know.

The singer broke down crying in court as she discussed Combs' "freak offs," a term for the mogul's alleged drug-fueled sex parties. She said that they made her feel "horrible" and "worthless" but that she continued to participate for "the one-on-one time" with Combs and out of fear that the rapper would become violent or find someone new.

Sean 'Diddy' Combs faces accusations of running drug-fuelled sex parties and committing violence against women over two decades. Prosecutors allege he used his team to conceal crimes.

Cassie claimed during her Tuesday, May 13, testimony that Diddy had a kiddie ‘pool filled with baby oil’ during alleged ‘freak offs’

Lawyers for Misa Hylton, who previously showed support for Diddy accuser Cassie, said that she was at the trial to support her son with the music mogul.
