Diddy Stevie J's Visual Reminder ... Everyone Parties with Puff!!!

Stevie J posted a video that is Diddy's biggest PR offensive to date ... and the message is clear -- check out who parties with Diddy, because it's virtually every big celeb in Hollywood.

The video is a highlight reel of Diddy's 50th birthday bash back in 2019 in Bev Hills, and the guest list is the Oscars meets the Grammys meets the ESPY awards.

Among the guests ... Kobe Bryant, Dr. Dre, Jay-Z, Mary J. Blige, Kim and Khloe Kardashian, Kylie Jenner, Post Malone, Naomi Campbell, Cardi B, Big Sean, Travis Scott, The Weeknd, Kanye West, Jaden Smith, Snoop Dogg, Queen Latifah, Kevin Hart, MGK, and on and on.

It's not hard to read between the lines -- with all the talk of sex parties, they're trying to show this is what really goes on behind closed doors at Diddy's parties.

Of course, both could be true -- celeb-packed back-tie events, but also sex parties outside the spotlight -- and that's what the feds are examining after last week's raids.

What's clear, however, since Stevie has been Diddy's biggest and most public ally ... Diddy is active in trying to shape a new narrative for public discussion, and reminding everyone exactly who's been happy to party with him.
