Kendall Jenner and Jacob Elordi's romance is seemingly getting serious with the family involvement.

​Following the 30-year-old model and the 28-year-old actor's romantic Hawaii getaway, the pair was spotted on a double date with Kendall's sister, Kylie Jenner and her beau, Timothee Chalamet, on Saturday, as per snaps shared by DeuxMoi.

​An insider spilled some details of the outing to People, noting that the group “have a lot of fun together," on the double date.

​The source further remarked that the foursome share "similar personalities and lifestyles," so they "all really get along."

​Moreover, Jacob and Timothee "already know each other and were friendly before Kendall and Jacob were getting close."

​The Oscar-nominated duo "spent a lot of time around each other during the award season and naturally run in similar circles," the source said.

​Noting more similarities between the Wuthering Heights actor and the Wonka star, the tattler stated, both "have the same attitude when it comes to fame. They're both actually pretty low-key. They like to stay out of the spotlight when they can. They have a lot of respect for each other."

​Kylie has seemingly approved Kendall's new fling as the source said that she already knows Elordi "and really likes him."

"She's excited Kendall is spending time with him," the bird chirped.

​It is pertinent to mention that Timothee and Kylie have been dating since 2023, while Kendall and Jacob sparked romance rumors since they were spotted hanging out together at the 2026 Coachella in April.
