They are 21 and he is 42.

However, DJ Khaled appeared to be having a great time on Monday when he spent time on a lavish yacht in Miami with Kylie Jenner and her best friend Jordyn Woods.

As the two females enjoyed some sun on deck, the record producer and radio personality was captured on camera enjoying a quick spin on a jet ski.

The three were using the stylish yacht that nightclub owner Dave Grutman of Miami Nightclubs owns.

DJ Khaled sat on the jet ski and snapped some selfies with his smartphone.

He travels in the same circles as the Kardashian and Jenner reality family.

Stormi, Kylie’s eight-month-old daughter, went out with her father, musician Travis Scott, as well.

As her mother carried the baby onto Grutman’s yacht, she looked to be dozing off in her car seat.

Kylie wrapped the toddler in a blanket and nestled her among pillows inside the yacht’s stateroom.

Kylie went on the deck to sunbathe and enjoy a drink with her pals after making sure her infant was deep asleep.

The young mother’s costume, consisting of body-hugging black Spandex and pale pink hair pushed back in a bun, seemed more appropriate for a club than a boat.

Despite this, Kylie continued to happily converse with her pals who were wearing bikinis.

After a wild night out celebrating her closest friend Jordyn Woods’ 21st birthday, who joined the boat party on Monday, she spent her day on the boat.

Celebrity performer Grutman organized a lively party at the well-known nightclub LIV, where the best friends celebrated the end of a glamorous weekend.

They both had the opportunity to sign the walls while having a great time at Liv, and they were given personalized medallions that said, “Liv on Sunday,” in reference to the nightclub.

Eventually, the wоmen were seen leaving the club together, Kylie holding onto her friend for support.

Grutman hosted the birthday celebrants at KOMODO, where the evening also featured an exquisite supper. 

A five-tier birthday cake was given to Jordyn to round off the elegant celebration.

“What a birthday cake,” wow Kylie posted a Snapchat video of the cake presentation along with the message, “Happy Birthday, @jordynwoods.”

There was more to this Miami party this weekend than Jordyn’s big 2-1. The BFFs have also been celebrating the introduction of Kylie X Jordan, their new line of cosmetics.
