Kendall and Harry sitting in a tree! Khloé Kardashian is opening up about Kendall Jenner and Harry Styles' St. Bart's trip — and their relationship status. The Keeping Up With the Kardashians star mused during an interview on Thursday, January 7, that she thinks they are an item.

"Do I think they’re dating? Yes," Kardashian, 31, told Entertainment Tonight. "I don't know if they're, like, boyfriend-girlfriend."

She added, "I would call that dating. [But] I don't know what they are. You know, you have 'the talk,' [and] I don't know if they've had that talk yet."

As previously reported, Jenner, 20, and the One Direction singer, 21, celebrated New Year's Eve together last week. The exes (the pair briefly dated back in 2014) got cozy on a yacht, flirted poolside and even hung out with Ellen DeGeneres and her wife, Portia de Rossi.

Despite their close bond, it appears Kardashian and Jenner have yet to chat about the tropical getaway. "Nowadays I don't know. People are weird with stuff. So, I don't know their title," Kardashian told ET. "But I mean, they were in St. Bart's together hanging out, so to me that's dating."
