Cassie Ventura, also known as Cassie, appeared solemn on Tuesday morning as she prepared for her highly anticipated court appearance in the sex-trafficking trial involving her ex-partner, Sean Combs, famously known as Diddy.

The 38-year-old singer, who is currently pregnant with her third child with husband Alex Fine, was seen heading to the Manhattan federal court wearing a stylish camel-colored trench coat, a brown turtleneck, and coordinating boots.

She paired her ensemble with black sunglasses and styled her hair straight.

Ventura is scheduled to give her testimony on Tuesday following a dramatic day of opening statements where prosecutors claimed that Combs, 55, once coerced a male escort into a disturbing act involving his then-girlfriend.

Assistant US Attorney Emily Johnson told the 12-person jury, which consists of eight men and four women, that the disgusting act allegedly made the “Long Way to Go” singer feel like she was “choking.”

However, when the male escort, identified as Daniel Phillip, took the witness stand later in the day, he claimed Ventura “told me to do it.”

He added, “And, apparently, I was doing it wrong because they both stopped me and told me I was supposed to let a little out at a time and not go full like — take a leak on her.”

Ventura’s testimony is expected to be very emotional, as she recounts some of the horrific details from her decade-long relationship with Combs, which took place from 2008 to 2017.

She has made some of her alleged experiences known already in a scathing rape lawsuit she filed against the “Bad Boy for Life” rapper in November 2023.

Ventura claimed in that suit that Combs abused her “physically and sexually” repeatedly as she “tried to escape his tight hold over her life.”

“Every time she hid, Mr. Combs’s vast network of corporations and affiliated entities found her, and those who worked for Mr. Combs’s companies implored her to return to him,” the suit further claimed.

Ventura and Combs settled their lawsuit within 24 hours, although the latter claimed the agreement was not an admission of wrongdoing.

In May 2024, CNN then released shocking surveillance video of the “Making the Band” producer dragging and beating the songstress in a hotel hallway in 2016. That damning video was already been played for the jury on Monday and is considered a key piece of evidence in Combs’ sex-trafficking case.

However, the disgraced music mogul’s legal team has reminded jurors that their client has a “bad temper,” “domestic violence is not sex trafficking” and he is being tried for the latter.

Combs — who is accused of hosting nefarious “Freak-Offs” — has pleaded not guilty to all the charges he is facing, including sex trafficking, racketeering and transportation to engage in prostitution.

It has been reported that his defense team plans to accuse Ventura of domestic violence on the stand in an attempt to take a stab at the “King of Hearts” singer’s credibility.
