The reality star confirmed her model sibling is seeing Harry Styles after cameras caught the couple kissing on a yacht during a New Year’s vacation to the Caribbean. (Hey, what are sisters for!)
“They were hanging out together. Do I think they’re dating? Yes. 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,’ Kardashian told Entertainment Tonight, using air quotes. “But I mean, they were in St. Barts together hanging out, so to me that’s dating. I would call that dating.”
Still, Kardashian, 31, insisted she doesn’t know how serious the romance is yet.
“I don’t know if they’ve had that talk yet,” she said, indicating that she and boyfriend James Harden have had that chat. “Do people still have the talk? You need the talk … I don’t believe in assuming what you are. That’s ridiculous.”
