The 'RIP' singer claimed that she is just "really tight" with the 25-year-old, as well as his sister Kim and the rest of their famous family.
When asked about the rumours by Glamour, Ora replied: "They're not true, but we're good friends. Really... like, we're tight."
She continued: "Kim's a cool girl. She's so pretty. I was a fan of her show, I love reality TV. The first time I met her was at a 'Watch The Throne' show, and I liked her bum.
"I was like, 'Kim, I love your show'. We had some dinner when she was over recently with Kanye. It was nice to catch up."
However, Ora ruled out making an appearance on Keeping Up With The Kardashians any time soon.
"No, I wouldn't go on the Kardashian TV show," she stated. "I don't think I could do a reality show, no."
The musician has previously dismissed suggestions that she is dating Drake.
