Khloe Kardashian says Harry Styles and Kendall Jenner are dating.

However, the reality TV star isn't sure if her model sister and the One Direction man are in a relationship.

The famous pair were pictured recently embracing on a yacht in Caribbean island Saint Barts.

Speaking to Entertainment Tonight, Khloe Kardashian confirmed that she believes the duo are seeing each other.

She said: "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. But I mean, they were in St. Barts together hanging out, so to me that's dating.

"You know, you have to have 'the talk' [and] I don't know if they've had that talk yet."
