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.

Veteran comedic actor Pat Finn — who starred in sitcoms like “The Middle” and “The George Wendt Show” — is dead from a cancer battle … TMZ has confirmed.

Family sources tell us Pat passed away Monday evening at his home in Los Angeles, and he was surrounded by his family.

Pat came up in Hollywood around the same time as his good friend Chris Farley. He and Chris attended Marquette University in 1987, played rugby together there … and were roommates in Chicago when they both joined the Second City comedy troupe.

Several of his co-stars and friends, including comedian Jeff Dye, have posted online tributes.

While Pat’s family sources would not confirm what kind of cancer he’d been fighting, there are reports he was diagnosed with bladder cancer several years ago.

Pat is survived by his wife Donna — to whom he’d been married since 1990 — and their 3 children.
