Aoki Lee Simmons, 21, Vittorio Assaf, 65, Kiss During Romantic St. Barts Trip

Aoki Lee Simmons and Vittorio Assaf could not keep their hands off each other.

Aoki, 21, and Assaf, 65, were photographed packing on the PDAs during their romantic getaway in St. Barts Tuesday. In the photos obtained by Page Six, the two were seen kissing by the beach.

Kimora Lee Simmons and Russell Simmons' youngest daughter, Aoki, rocked an olive-green bikini with a tribal print on the front. Meanwhile, the Serafina co-founder opted to go topless with light-blue-and-white printed board shorts.

In some snaps, Aoki seemingly posed while Assaf held the phone to take photos. Aoki also shared a series of bikini photos from the Caribbean island on Instagram. However, she didn't include any shots of her rumored beau.

"Girls (possibly mermaids!) on film," she wrote in the caption, with a movie camera, smiling face with halo and water wave emojis.

The post received several comments from her fans. Many disapproved of her romance with Assaf due to their 44-year age gap.

"Girl, now I like you, but messing with a 65 year old man is ridiculous," one commented.

Another added, "Our black Queen went to HAVARD [sic] as a model she choose [sic] to be with a 64 years old man as a boyfriend ?! She's only 21 ?! Why ?! How ?! And she's educated !!" with a crying face emoji.

"@kimoraleesimmons your daughter on the beach kissing an old man with worms!" a third person wrote tagging her mom's account.

"I know you're not with that old man [three face with tears of joy emojis] hope it's a movie scene," another user added with a face with open mouth emoji.

According to Page Six, Aoki shared a video of herself wearing the same bikini when she was photographed with Assaf on March 27. However, the clip has since been deleted.

Meanwhile, Assaf recently shared a photo of him alongside one of his pals. In the snap, both were holding a plate from the Gyp Sea restaurant, where they were presumably dining, as they grinned at the camera.

"Friends since 25 years ! Proud of you," Assaf wrote in the caption with a thumbs-up emoji.

The post also received several responses from the netizens. One said they visited the businessman's page "after the Aoki situation" with multiple laughing emojis. Several also seemingly mocked him for his relationship with the much younger personality.

"This dude should be ashamed," one person commented.

Another commenter wrote, "Why are you with Aoki? Let the girl grow up."

A different netizen said it was "very creepy."

Meanwhile, another user pointed out that his friendship with his pal was longer than Aoki "has been alive."

Page Six reached out to Aoki's and Assaf's reps for comment but did not immediately get a response.
