Over the weekend, Kimberly went HAM on Instagram tearing into Tristan, Khloe, and his first baby mama Jordan Craig. It seems everything was set off after Tristan wrote a heartfelt note to his son Prince on his birthday. He said, "Happy birthday Princey!!! I’m soo lucky to have you as a son papa. Your heart and soul is pure gold. Your sister is soo lucky to have a big brother like you to watch and protect her. Daddy Loves you baby boy ❤️🙏🏾💪🏾🤘🏾❤️"
