There are speculations that Kylie Jenner is slowly disassociating herself from her older sisters in order to make a name for herself now that she's 18 years old.

But does it mean dissing her older Kardashian siblings, specifically Kourtney Kardashian, by hanging out with her ex-partner Scott Disick?

According to a report, Kylie Jenner and her boyfriend Tyga reportedly partied with Kourtney Kardashian's ex, Scott Disick, in West Hollywood.

Kourtney Kardashian was allegedly pissed at the youngest of the "Keeping Up With The Kardashians" sister for being so friendly with her ex-partner despite the bad blood between Kourtney and Scott.

"Kourtney is obviously hurt that Kylie is still partying with Scott," an insider reportedly told Celeb Dirty Laundry. "But, she's not surprised."

"Her little sister has turned into a ruthless fame-hungry monster, and all she cares about is fame and fortune, and making sure everyone knows she isn't a Kardashian. Scott is cut off by the Kardashians, what better way to prove Kylie isn't a Kardashian than to keep hanging out with him?"

Because Tyga was with Kylie Jenner during the party, there are also speculations that the rapper might be a bad influence to the reality star. Is Tyga leading Kylie Jenner farther and farther away from her family?

Before the alleged Kourtney Kardashian issue, Kylie Jenner and Tyga's has been in hot water for the rapper's raunchy song "Stimulated." Some believe that the song is about Kylie Jenner, who just turned 18 this August.

Gossip Cop quoted a line in the song: "They say she young/I shoulda waited/She a big girl, dawg/When she stimulated."

Is Kylie Jenner offended about Tyga's "Stimulated" lyrics? Not really, according to a source close to the circle of the "Keeping Up With The Kardashians" star.

"Kylie thinks Tyga is a musical genius," an insider told Hollywood Life. "She's so proud to call him her boyfriend and nothing could ever change that. She knows raunchy music is just part of the rap game and Tyga's style."
