Kendall Jenner and Jacob Elordi’s romance has officially reached the next level.

“Kendall and Jacob have taken that next step in their relationship and they’ve made things official,” a source exclusively told Page Six.

According to the insider, the supermodel “definitely sees a future” with the Oscar nominee.

The reality star, 30, and the “Euphoria” actor “have basically been inseparable since they started dating,” the source said. “They’re just in that phase where they want to do everything together and things have gotten pretty serious.”

Ahead of Elordi’s 29th birthday on Friday, the “plan is for them to celebrate together in Australia.”

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

The milestone comes after Page Six reported that the “Kardashians” star and the “Frankenstein” actor — who sparked romance rumors in February — were “not rushing to label anything or call each other boyfriend/girlfriend yet,” and that “neither of them are seeing anybody else but it definitely seems like it’s heading in that direction.”

A source previously told Page Six that Jenner 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.”

Last month, the duo was spotted on a romantic getaway in Hawaii, which we were told brought the twosome even closer.

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

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