Russell Simmons’ daughter Aoki, 21, is reportedly dating wealthy 65-year-old restaurateur Vittorio Assaf

Twenty-one-year-old Aoki Lee Simmons, the youngest daughter of Russell Simmons and Kimora Lee Simmons, was spotted kissing a 65-year-old man during a romantic vacation in St. Barths on April 2, Page Six reported.

The sexagenarian Aoki locked lips with is Vittorio Assaf, the co-founder of the Serafina chain of restaurants. The pair were having a day out at the beach when the photos were taken. Besides the kissing, Aoki, who was wearing an olive-green bikini, also posed for pictures that Assaf took with his phone.

The pair were also pictured taking a dip in the sea. Aoki later shared photos of her vacation on Instagram – but her beau Assaf wasn’t included in those snaps. The photos in question raised eyebrows on social media, but Aoki later shared an Instagram post with the caption, “errr well now I know why folks were calling me.”

The model and Harvard graduate’s mother, Kimora, 48, seemingly reacted to her daughter’s public display of affection with the 65-year-old on her Instagram story. “On my last nerve right now!” she captioned alongside a video of a mother panda dragging her cub.

Russell Simmons, on the other hand, posted a throwback photo with his daughter and expressed his love for the 21-year-old. “Throw back from last fathers day nyc …bode bikram yoga express class .. vegan lunch cryotherapy vitamin drip … all around amazing day ❤️,” the 66-year-old shared on Saturday, per Page Six. “@aokileesimmons love you always im always waiting for any call any time ❤️.”

Meanwhile, a source confirmed to PEOPLE that Aoki and Assaf are currently dating. “Aoki and Vittorio are spending time together and enjoying each others’ company,” the source said.
