In his first interview since being released from the same prison that houses Diddy, former NBA player Sebastian Telfair tells TMZ what it was like being locked up with the music mogul.

Telfair chatted with our cameraperson just hours after being released from FCI Fort Dix, revealing it was rough for him getting locked up after living such a successful life, but he “couldn’t imagine how Diddy felt.”

Still, Telfair says the Bad Boy cofounder is making the most of it and staying in good spirits.

He said, “Diddy’s holding it down. He’s doing what he gotta do. And where he’s at, they’re going to help him.”

LWD — livestreaming while driving — is why TikToker Tea Tyme is behind bars on Christmas Eve … nearly 2 months after she allegedly ran over a pedestrian, cops have her in custody.

Tea Tyme — or Tynesha McCarty-Wroten, IRL — was arrested Tuesday in Zion, IL and booked for 2 felonies … reckless homicide and aggravated use of communications resulting in death.

As that second count describes … cops say Tynesha was livestreaming Nov. 3 in the suburb north of Chicago while she was driving, and ran into 59-year-old Darren Lucas as he walked across an intersection.

On her stream, you could clearly hear a thud, and then she said, “F***, f***, f***, I just hit somebody.” You could also hear a child in the car ask what happened … and then the stream cut off.

Cops say Tynesha called 911 and remained at the scene to speak to cops. Darren was rushed to a hospital, where he was pronounced dead.

Diddy‘s legal team is ripping Judge Arun Subramanian, accusing him of crossing a line with the 50-month sentence … and acting more like a juror than a judge.

Diddy filed a new appeal late Tuesday evening, demanding his conviction be overturned, and his release from prison … or, at the very least, his sentence be lightened. While his lawyers have previously filed multiple appeals, this one singles out Judge Subramanian for acting as the “thirteenth juror” in Diddy’s criminal trial.

In the docs, lead appeal attorney Alexandra Shapiro claims the judge’s “draconian” 50-month sentence is based on the conduct for which the actual jurors acquited Diddy — namely, the racketeering and sex trafficking counts.

Shapiro claims Subramanian incorrectly said during sentencing he could consider Diddy’s behavior related to the more violent charges — even though he’d been acquited of them — which she calls a violation of Diddy’s constitutional rights.

In previous appeals, Diddy’s team has also argued he did not actually set up the travel or payment for the male prostitutes … and, therefore, did not violate the Mann Act.
