"Honestly, people have it all wrong," she says when Ellen asks her to clear up all the reports. "We're not broken up."
Kylie refuses to even call Tyga her boyfriend, although the evidence is pretty obvious.
"We just, honestly, we became best friends before anything happened, so I think that that's awesome," she says. "And we're just, like, hanging out all the time."
"We're still together," she adds.
Kylie recently belatedly celebrated Tyga's birthday, posting a Snapchat video on Tuesday of herself and her mother, Kris Jenner, with the rapper before he blows out the candles on a birthday cake. The two also made it clear they were still an item on Sunday night at the American Music Awards, which they left hand-in-hand.
Last week, Kylie opened up about her love life in a candid post on her website and app, calling herself a "relationship girl."
"I've never believed in the idea of casual dating or being with two people at once," she wrote. "I feel like I only have room for one person in my heart and I want to give whoever I'm with all the attention they deserve."
"I'm not afraid to show who I'm dating, but I'm also not about to talk about every little detail of my relationship," she added. "Living in the spotlight, people think they know everything about me, but they don't. I've never believed in the idea of the public knowing everything about my relationship and every time I break up and make up."
