Kylie Jenner breaks down in tears over Tyga!

We hear things have been strained between Kylie Jenner and Tyga recently, as the reality star's brother Rob Kardashian is now dating her boyfriend's ex and baby mama Blac Chyna.

But it seems like there's been trouble brewing between the pair for some time.

In a new teaser for Keeping Up With The Kardashians, Kylie, 18, can be sobbing about her relationship with Tyga to her sisters Kourtney and Khloe Kardashian.

“Did you get in a fight?” Kourt, 36, asks as Kylie wipes tears from her eyes.

“It’s just like…I don’t know what to do about T,” she responds, before the clip ends.

Interesting…..

The episode was shot in November last year, around the time the pair reportedly briefly split following speculation that Ky found something suspicious on the rapper’s computer.

Days later the couple appeared to have worked things out as they stepped out together and put on a united front.
