Kylie Jenner choose to call a truce with Blac Chyna because she could see how happy she was making Rob Kardashian.
A source said: “Kylie is over the relationship. It was tough for her in the beginning. But she sees how happy he [Rob] is and all she wants is for him to be happy. The general consensus in the house is ‘Praise Chyna! Don’t go!’ They finally got the brother they always knew back.”
