Just last weekend, Kendall Jenner and Harry Styles were seen vacationing together and packing on a lot of PDA, and while the two have yet to comment on the obvious romance, Jenner's older sister Khloé Kardashian has opened up about it for her.

"Do I think they're dating? Yes," Kardashian told "Entertainment Tonight." "I don't know if they're like boyfriend-girlfriend. Nowadays, I don't know. People are weird with stuff. So, I don't know their title. But, I mean, they were in St. Barts together hanging out, so to me that's dating."

Several photos of Jenner and Styles, who have been romantically linked before, getting cozy and kissing in their bathing suits on a yacht were captured, so the pictures really did seem to speak for themselves, and Kardashian agrees.

"I would call that dating," she said. "[But] I don't know what they are. You know, you have to have 'the talk' [and] I don't know if they've had that talk yet. Kendall doesn't want to get hurt, so she's proceeding with caution. She knows what the deal is."

Judging by the photos, it seemed as though the two were having a blast together, but it looks like it has potential to turn into something more. "He'd love to have a proper girlfriend," a source close to the One Direction member told Us Weekly. "If she's keen to take it to a serious level, he would be too."

Thankfully, the 20-year-old reality star's famous family is on board, especially her mother Kris Jenner. "Kendall can get a bit too serious, but Harry has a way of bringing out her silly side. This is one of the many reasons Kris loves seeing them back together. Plus, Harry is a complete gentleman and has a big heart. There's not a mean bone in his body," a source told Hollywood Life. "Kris is so relieved that Kendall waited for someone special to get involved with. Kris says Kendall could have any guy, but was patient and it paid off big time! Kris is just over the moon about her daughter's reunion with Harry. She always knew he was the one for her. She adores Harry and has never seen Kendall happier. Call it mother's instinct, but Kris knew the two would get back together one day."
