Did Kylie Jenner, Tyga Break Up Again? Sources Say They're Still A Couple Despite Lack Of Appearances Together

Rumors have been swirling for weeks suggesting that Kylie Jenner and boyfriend Tyga have called it quits. The stories date back to Nov. 19 when Tyga arrived at his 26th birthday party without the star of E!'s "Keeping Up With the Kardashians." Kylie, 18, recently appeared on "The Ellen DeGeneres Show" where she dispelled the rumors, but a series of solo appearances since has fans asking questions.

According to a report from TMZ, the beauty mogul and her rapper beau are still an item. Sources tell the publication Kylie proposed a deal with Tyga regarding their careers. The source says they've agreed to give one another professional space to avoid muddling one another's brands. As such, they often arrive to events alone -- even ones like Rihanna's Diamond Ball on Thursday, which both were invited to and attended.

While sources claim Kylie and Tyga are still going strong, there is one member of the Kardashian-Jenner family who is reportedly rooting for them to fail. As International Business Times previously reported, Kendall Jenner, Kylie's 20-year-old sister, was said to be elated upon hearing that Kylie and Tyga, or Kyga as they've been dubbed by fans, were headed for splitsville. The model has reportedly been getting along with Kylie much better now that her "world doesn't revolve around Tyga." Kylie is said to be spending more time with her sister, which Kendall, 20, reportedly appreciates.

Kendall's alleged distaste for Tyga will be showcased during Season 11 of "KUWTK." Previews for the season show the sisters butting heads after Kylie invites Tyga along on a family trip. Kendall expresses to her sister that she had hoped they'd be able to bond during their vacation sans boyfriends. Kylie's response to her sister is not shown in the clip.

Kylie has not responded to rumors that she and Tyga are broken up. Be sure to tune in to "KUWTK" Sunday at 9 p.m. EST for the family's vacation episode.
