Kylie Jenner, the youngest of the Kardashian-Jenner brood, has long been rumored to be dating Tyga. She apparently was “livid” after momager Kris Jenner discussed her alleged relationship with the rapper, Radar Online reported Thursday. Things were so intense that the two had a “blowout fight.”

Kris Jenner spoke to Ryan Seacrest to promote her new cookbook, “In the Kitchen With Kris,” and talked about her youngest daughter. This apparently infuriated the teenager. “Kylie did not give her mom permission to discuss her relationship with Tyga to anyone, including Seacrest,” a source told Radar Online.

But Kris Jenner never said the two were dating when she spoke with Seacrest. “Kylie isn’t dating anybody,” she said during the interview. “Tyga used to live across the street for a long time, and now he lives next door to Khloe. Everyone’s always around and with the way I cook, they’re not leaving.”

The drama could have arose because things between Kris Jenner and Kylie Jenner are apparently contentious. “Kylie told her mom to stay out of her life and keep ‘focusing on Kim as she always has,’” an insider told Radar Online, in reference to Kim Kardashian, 34. “Kylie and Kris have a real bad relationship right now and Kylie is doing everything that she can to defy her mom.”

Rumors Tyga, 24, and Kylie Jenner were dating have been buzzing for some time. The two were recently spotted in England’s Gatwick Airport, before traveling to France and Athens.

But her dating life isn’t the only thing that has people talking. The teen has widely been suspected of getting lip injections. Just a few years ago, she had thinner lips, but now she posts numerous Instagram selfies that reveal a luscious pout.

"How long are we gonna talk about this lip thing? lmao," she tweeted Monday. "Let's get our lives together guys and talk about some important s---." She added: "Just talk about something new at least. I'm bored."
