Check out Kylie, Tyga, Rob and Black Chyna's funny family tree

We all know Tyga is in a relationship with Kylie. He already has a three year old son with Black Chyna, Chyna now is pregnant for Kylie's brother, Rob Kardashian. The thing is, how would the family tree look if Tyga and Kylie were to have a kid together? 


TMZ unravelled how things might look like, hypothetically., See their break down of the family the after the cut.


- Tyga and ex, Blac Chyna, spawned King Cairo ... he'll be half brother to Rob and Chyna's unborn kid. Tyga then becomes an uncle to Cairo's new half sibling ... by virtue of Rob and Kylie's sibling relationship.

- If Tyga and Kylie popped out a kid ... that'd give Cairo another half sibling ... Tyga and Kylie's hypothetical kid would be half cousins with Rob and Blac's kid.

- Rob would be Cairo's stepdad ... and an uncle to Tyga's and Kylie's kid -- with Blac as aunt to King Cairo's half sibling.

Very complicated and confusing...lol
