Kylie completely breaks down and CRIES over her boyfriend Tyga

It's fair to say that when we were 18 years old, we probably cried about every single little thing that would happen in a relationship. It's completely normal.

For the most part, Kylie Jenner seems like she has it all together, she's confident and she's never seen breaking down.

Until now though, as at the end of last night's episode of Keeping Up With The Kardashians, a clip for next week's show saw Kylie completely fumble and cry over her boyfriend, Tyga.

In the clip, she is heard saying, "I just, like, don't know what to do about T."

She's then seen sobing, with Kourtney trying to console her, but before it went any further the clip stopped.

Relationships can be mega-difficult at any age, but we think this outburst might be because of the allegations Tyga cheated on her with a Brazilian model. 

The model, Annalu Cardoso, 23, allegedly slept with the rapper while Kylie was "out of town."
