Kendall Jenner and Harry Styles have been spending a lot of time together lately, causing speculation about whether or not they're a couple. While neither the model nor the One Direction frontman have much to say about their potential courtship, Jenner's sister and "Keeping Up With the Kardashians" star Khloé Kardashian is ready to speak out.

In an interview with Entertainment Tonight, the 31-year-old reality star said she is fairly certain Jenner, 19, and Styles, 21, are dating, though she was not certain they'd given it the official title of "boyfriend-girlfriend." Kardashian said she wasn't sure the pair had "'the talk'" yet, but said she would definitely classify the amount of time they've been spending together as a relationship. She went on to say that in this day and age "people are weird" about relationships, so it's hard to say.

"Do I think they're dating? Yes," she said. "I don't know if they're, like, boyfriend-girlfriend. 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."

Dating rumors began swirling after Jenner and Styles were seen spending time together in Anguilla on Dec. 30. As was previously reported the rumored couple, who have dated in the past, were photographed getting cozy at Blanchard's, a local restaurant. The photos are blurry, but it is clear both Jenner and Styles are in them. The photo has made it's rounds on Twitter with fans of the pair going wild over their possible reunion.

Jenner and Styles dating briefly in 2013. They got together in November of that year and were spotted out together several times, though nothing was confirmed.
