Things are escalating between Kendall Jenner and Jacob Elordi. Following their alleged Coachella hookup (an iconic start to any relationship), the pair were spotted vacationing on a beach in Hawai‘i, before being photographed on a double date with none other than Kylie Jenner and Timothée Chalamet. And turns out everything got way more real in Hawai‘i.

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

The source adds that Kendall’s “really happy right now and loves how easy things feel” and that “her friends and family can see how much she likes him.”

And SPEAKING of family, about that double date. Per the anon insider, “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. Jacob’s just a really good guy. He’s super respectful and easy to be around, and it’s becoming a lot more serious than she expected.”

Meanwhile, yet another insider (everyone’s being very chatty) tells People that Timmy and Jacob have the same attitude when it comes to fame” and are “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.”
