Kendall Jenner and Jacob Elordi’s relationship has leveled up.

A source exclusively told Page Six that the couple’s romantic getaway to Hawaii has brought the supermodel, 30, and the actor, 28, even closer.

“Kendall really didn’t expect to be this into him this fast, but Hawaii kind of changed everything,” the insider said. “They got super close on that trip, and it definitely made their connection stronger. It’s becoming a lot more serious than she expected.”

According to the source, the “Kardashians” star is “really happy right now and loves how easy things feel” with the “Frankenstein” actor.

“Her friends and family can see how much she likes him,” the insider said. 

The source added that Jenner has especially enjoyed being able to spend time with her younger sister, Kylie Jenner, while also getting to know the men in their lives together.

The sisters were recently spotted on a double date with Elordi and Timothée Chalamet in Los Angeles on last Saturday. Elordi appeared to be driving with Kendall in the front seat of a car, while Kylie and Chalamet sat in the backseat with the group’s friend, Renell Medrano.

“It’s been really fun for her and Kylie being able to hang out with guys who genuinely get along and fit naturally into their lives, because they honestly haven’t really had that in a long time,” the source told Page Six.

“Jacob’s just a really good guy,” the insider said. “He’s super respectful and easy to be around, and it’s becoming a lot more serious than she expected.”

Reps for Kendall and Elordi did not immediately respond to Page Six’s requests for comment.

As previously reported, Kendall was “a little hesitant at first” of striking up a romance with Elordi “because of the friendship” they share.

“They’ve known each other forever and run in the same circles,” the insider said, noting that while the two have been around each other for years, their dynamic has “definitely shifted” recently.

“They’ve actually been spending time together for a couple months now, just keeping it quiet,” the source explained. “They’ve just been hanging out more and seeing where it goes.”

According to the insider, the reality star approached the connection cautiously.

“Kendall’s really private so she’s taking it slow,” the source said. “She’s not the type to jump into something, especially with someone she’s been friends with.”

Kendall has previously been linked to NBA star Devin Booker, Bad Bunny and Harry Styles, while Elordi’s past relationships include Olivia Jade and Kaia Gerber.
