Kylie Jenner has always put on a poker face regarding her relationship troubles with Tyga ,but in a sneak peak at an upcoming episode of Keeping Up With The Kardashians, the 18-year-old showed her vulnerable side.
In scenes filmed last October,she broke down in tears over their relationship which has been rocked by numerous cheating allegations.

“I just, like, don’t know what to do about T,” she sobs as Kourtney tries to console her.

Before they can say anything, Kylie gets up and walks off while still in tears.
