He certainly had a July 4 weekend to tell his school pals about.

Sean “Diddy” Combs’ White Parties in the Hamptons were not known for being family-friendly — which Justin Litovsky, now 30, rapidly found out when he was just a 6-year-old kid with well-connected parents.

They unknowingly attended Diddy’s July 3, 1999, “afternoon barbecue” only to find it loaded with revelers literally partying like it was 1999.

“I remember a lot of weed and a bunch of topless women in the pool and around the pool,” Litovsky told The Post.

“I actually wanted to get in. Any time we went anywhere with a pool, I wanted to swim.”

At the time, Litovsky admitted, “I didn’t know if t–s were a good thing or a bad thing. But I hoped to jump in.”

Justin Litovsky attended a Diddy party at the age of 6. He saw topless women, recognized the scent of weed and posed for a pic with the notorious mogul.

The mother of young Justin, Maya Litovsky, did not have much to mull over. “I did not give my son the opportunity to get in there,” Litovsky, now an influencer, told The Post.

“There were bottles everywhere and naked women. I wasn’t sure if this was appropriate or normal. I wondered about how kids were allowed into the party to begin with.”

Guests included a Cohiba-puffing Jay-Z, platinum-tressed Lil’ Kim, Donna Karan and Tyson Beckford with a not very child-appropriate T-shirt that blasted “F—k Giuliani,” then New York’s law-and-order-favoring mayor.

Diddy would go on to set a kid curfew at future parties (“If child welfare come here in 30 minutes, that’s on y’all,” he joked from his Hamptons balcony in 2007. “My kids are downstairs — 15 minutes, the kids have to go”) — but in 1999, Justin remembers being the sole grammar schooler.

“I don’t remember seeing one other child,” he said. “I’m normally the type to want to go play [with other kids].”

Jay-Z puffed a Cohiba and wore a T-shirt that hyped his just-founded fashion brand.

Tyson Beckford expressed his feelings for then-Mayor Giuliani while attending Diddy’s party in 1999.
If a minor in attendance was a problem for Diddy, guests would never know it. Justin and Maya were there with the photographer David Allen (father to Justin and husband to Maya). Allen remembers buzzing around the hoedown, snagging pictures of celebrities, as was his job.

As evidenced by the pictures obtained by The Post, Diddy — sunglassed and surly-looking — was happy to pose for a picture with Justin.

Justin, who said his father got him in pictures with lots of celebs — including Magic Johnson, Patti LaBelle and Keith Richards — found the Diddy experience a bit of a mixed bag: “I don’t look like I have a normal smile in the pic,” he said, perhaps disturbed by some of the adult goings-on around him.

Diddy was arrested by federal agents last month on charges including racketeering and $ 3 x tr@fficking. He is being held in the Metropolitan Detention Center in Brooklyn, awaiting trial. He has pleaded not guilty.

Back in 1999, Justin and his parents handled the elite bash by moving away from pot smoke, bottles of booze and sun-worshipping libertines without tops.

They didn’t think much of it back then. Recently, though, with the outrageous $ 3 x-oriented charges leveled against Diddy, they can’t help but wonder what they got themselves into.
