RJ Hampton — a former NBA first-round draft pick — berated a woman, told her to “shut up” and admitted to leaving bruises on her body … and the disturbing behavior was caught on video.

Tiffany JeffcoatA Social media influencer who shares a child with Hampton, posted the footage of the 23-year-old basketball player to her TikTok page on Monday.

Jeffcoat claimed the video was filmed at a hotel in Oklahoma after she and her 13-month-old son had just traveled 11 hours to see RJ

In the video, RJ can be heard calling Tiffany “a bitch” – before they began discussing what appears to be a recent incident of domestic violence between the two.

Tiffany can be heard telling Hampton that she has bruises on her arms that “came from your hands.”

“Of course they did,” Hampton replied… before adding, “Did I hit you, did I hit you?”

When Tiffany seemed to admit that wasn’t the case, Hampton replied, “Well, shut up.”

Later in the video, as the two argued over a trip Tiffany took to Miami, Tiffany told Hampton, “My mom is more of a parent to him than you ever were.”

“I don’t care if your mother is dead or alive,” Hampton replied. “Keep your mouth shut.”

The video then ended with Hampton asking Tiffany to pay for her hotel room herself.

In two other videos Jeffcoat posted Monday, she also claimed that at another point during the day, RJ “literally grabbed (our son) off the ground, walked outside, jumped in the car and left.”

She said through tears that Hampton didn’t take any of the toddler’s belongings. In her caption to the video, she claimed she called the police, but they told her it was a civil matter.

In a follow-up video, apparently filmed hours later, Tiffany said she still hadn’t heard from RJ

No further video updates were released – although Jeffcoat shared a picture of the sleeping toddler on her Instagram Stories on Tuesday with the caption, “Thank you to everyone who reached out.”

The Delaware Blue Coats — RJ’s current team and G League affiliate of the Philadelphia 76ers — said in a statement to TMZ Sports: “The organization is aware of the footage and is investigating the matter.”

Hampton – a former five-star high school basketball prospect – was selected No. 24 overall by the Milwaukee Bucks in the 2020 NBA Draft.
