Cassie is confirming that her romance with Sean “Diddy” Combs came at the same time as his relationship with Kim Porter.

The 38-year-old pregnant “Me & U” singer spoke out during Day 2 of the ongoing sex trafficking trial.

The 55-year-old music mogul was arrested in 2024 for alleged sex trafficking, prostitution, racketeering conspiracy, sex trafficking by force, fraud, or coercion, as well as transportation to engage in prostitution.

During her testimony, Cassie said that Diddy was dating her and Kim Porter, who passed away in 2018, around the same time.

She recalled having sex for first the first time with Diddy while high on drugs on a boat in Miami. She was his artist signed to Bad Boy Records, 17 years his junior.

“I was drinking wine, then started to take drugs, a blue dolphin ecstasy pill. Sean gave it to me, I had never taken it before. I was just out of it, laughing, didn’t know what it was until a little bit later.”

She recalled feeling “euphoric” on the drug. “You are just really high, sensitive to touch and all of your senses.”

She said that after the Miami trip, they began to spend more time together, but their relationship “was not public for many years.”

“He just didn’t want it to look bad, but also knew it was because of his children and personal things like his family,” Cassie said, confirming she was speaking about “Kim Porter.”

Cassie also said Diddy‘s mood “swung different ways quite a bit.”

“Make the wrong face and the next thing I knew I would get hit in the face,” she testified. “He would say, ‘Watch your mouth.’”

Cassie and Diddy dated on-and-off for more than a decade before their split in 2018. Find out when their relationship first became sexual.

Kim and Diddy started dating in the ’90s, and welcomed their first child Christian in 1998. They broke up in 1999, and reconciled in 2003. In 2006, they welcomed D’Lila and Jessie James. They split for good in 2007, but continued to co-parent until Kim‘s death in 2018.
