Los Angeles, Sep 25 (IANS): Reality TV star Kylie Jenner has denied rumours that she's engaged to her boyfriend Tyga.

In a new video posted on her personal website, Kylie and her elder sister Kim Kardashian addressed the rumours that Tyga referred to her as his fiancee and that she "dethroned" Kim, reports aceshowbiz.com.

"You're in bed with Kim and Kylie!" the sisters opened the video showing them lying on a bed. Kim then quickly jumped into question session, "Wait, so I had some questions I wanted to ask you. It's about rumours."

The pregnant reality TV star was curious about the rumours of Kylie's engagement as saying, "Why did Tyga call you his fiancee? I was like dying to know."

Kylie made it clear that they're not engaged yet. She said Tyga poked fun at a video of rapper Logic he posted on Instagram earlier that day. "He was making fun of an Instagram he posted 30 minutes before," Kylie revealed. "He knew there was this guy who was on Instagram who was like 'I don't like nobody. I just play with my fiancee and my little dog.' "

Kim then shifted the subject to the rumours saying that Kylie "dethroned" her. "How do you feel that you have dethroned me?" Kim said. As Kylie tried to explain that it was impossible, Kim interrupted, "I love it, I need some time off."

The 34-year-old reality TV star then jokingly said, "I mean, honey, let's be real. You gotta put in a few years before you actually dethrone me." However, Kim admitted that she would pass on the baton to Kylie. "But I want to pass on the baton to you. Who better to pass on the knowledge to?" Kim said.
