Sean 'Diddy' Combs' White Party adultery shocks attendee: 'I saw naked women when I was 6'

He must have had a 4th of July weekend to tell his school friends about.

Sean “Diddy” Combs' white parties in the Hamptons weren't known for being family friendly; Something Justin Litovsky, now 30, quickly discovered when he was just a six-year-old kid had to do with parents.

They unwittingly attend Diddy's July 3, 1999, 'Afternoon Barbecue' only to find it's literally partying like it's 1999.

“I remember a lot of weed in and around the pool and a bunch of topless women,” Litovsky told The Post. “I actually wanted in. Whenever we went somewhere with a pool, I wanted to swim.”

At the time, Litovsky admitted, “I didn't know if t–s was a good thing or a bad thing. But I expected to jump.

Young Justin's mother, Maya Litovsky, didn't have much to worry about. “I didn't give my son a chance to go there,” Litovsky, now an influencer, told the Post.

“There were bottles and naked women everywhere. I wasn't sure if it was appropriate or normal. I was surprised how the kids were allowed to start the party.”

Guests included a Cohiba puffing Jay-Z, platinum-tressed Lil' Kim, Donna Karan and Tyson Beckford in a T-shirt not fit for a baby that blasted F-K Giuliani, then the law-and-order mayor of New York.

Although Diddy would go on to set a children's curfew at future parties — “If Child Welfare gets here in 30 minutes, it'll be for you,” he joked from his Hamptons balcony in 2007. “My kids are downstairs – 15 minutes to have kids to go,” remembers Justin as the only grammar schooler in 1999.

“I don't remember seeing another baby,” he said. “I'm usually the type that wants to go play [with other kids]”

If a minor in attendance was a problem for DD, the guests would never know it. Justin and Maya were there with photographer David Allen (Justin's father and Maya's husband). Allen remembers, buzzing around the hoedown, snapping pictures of celebrities, as was his job.

As evidenced by pictures obtained by The Post, Diddy – wearing sunglasses and looking surly – was happy to pose for a picture with Justin.

Diddy's experience seemed like a bit of a mixed bag for Justin, who said his dad got him in pictures with a lot of celebrities, including Magic Johnson, Patti LaBelle and Keith Richards: “I don't seem like my normal smile in pictures,” he said, perhaps around him. Adults are upset about something happening.

DD was arrested by the feds last month on racketeering and sex trafficking charges. He is currently in the Metropolitan Detention Center in Brooklyn, awaiting trial. He pleaded not guilty.

In 1999, Justin and his parents hosted an elite bash that shunned pot smoke, booze bottles and sun-worshipping without tops.

They didn't think much of it then. Recently, though, with abusive sex-based allegations against DD, they can't help but wonder what they've gotten themselves into.

“We didn't see people having sex, but we left at 9:30 p.m.,” said Maya. “The party continued and no one was getting out of the pool. So, who knows what happened.”
