Aoki Lee Simmons, 21, told friends her brief romance with Vittorio Assaf, 65, already ‘100% done’: sources

Kimora Lee Simmons is furious about her daughter’s new romance with Serafina founder Vittorio Assaf, who’s 43 years her senior, according to sources.

But we’re told Aoki Lee Simmons’ worried mom need not fret — because it’s already over!

It turns out the model’s PDA-filled getaway with the 65-year-old restaurateur was just a fling.

“It’s 100% done. They’re absolutely not dating,” a source close to Aoki told Page Six.

Then again, Simmons referred to Assaf as her “boyfriend” multiple times during the Instagram Live videos she posted from their romantic St. Barts vacation.

In one clip, the 21-year-old even revealed he’s the “second boyfriend” she’s ever had while taking her followers on a tour of his St. Barts property.

After Page Six posted exclusive pics of the pair smooching on the beach, the source told us Aoki said, “Of course, I’m not with him. I was never with him,” when they spoke to her on Monday.

Still, Aoki appeared more than happy to vacation with the restaurant whiz at his island home.

“I’m the happiest person to ever happy right now,” she said via social media while giving the house tour.

At one point, she even showed off his shoes, saying, “Look at how huge his shoes are. That makes me really happy. He’s [6-foot-4],” she gushed.

A source, who knows Assaf, described him as an “older man with little boy charm.”

“He’s always loved younger beautiful women. He’s gotten older, but his taste hasn’t changed,” the insider said.

“I wouldn’t be surprised if he’s out with another young girl tonight!” they added.

Another source — who is Aoki’s senior by decades and told us they slept with Assaf many years ago — added that one reason women fall for him is thanks to his impressive endowment, and they don’t mean financially!

“It’s the biggest… in New York,” the insider, who was surprised he was with someone as young as Aoki, said.

Meanwhile, Aoki’s father, music mogul Russell Simmons, has seemingly given the pair his blessing — claiming he’s not stressing over his daughter’s dating decision.

“All I can do is offer my advice and unconditional love,” he told TMZ.

Our first source believes Aoki may have alerted her father to stories coming out about the controversial romance out of panic, but insisted, “they are not dating.”

Despite video clips of Aoki boasting about wanting gifts from stores like Bulgari and Cartier, the source said she’s not materialistic and it’s all “absurd.”

“She’s not even like that. She doesn’t care about jewelry. She doesn’t have Hermes. It’s not even her. She doesn’t even care about expensive things like that. She’s like more of a geek,” the source said. 

The Harvard grad was back to mingling with the Ivy League crowd on Saturday — where she dazzled in a pink satin dress at Columbia Law School’s annual Barristers’ Ball at Pier Sixty in Manhattan.

She did not get back to us when we reached out for comment and Assaf was not available.
