The Kardashians haven’t reacted much publically to the news of Rob and Blac Chyna’s engagement. Tyga on the other hand has been forced through social media to address it and go on the defensive.

The California rapper is currently dating Kylie Jenner but more prevalent is that he used to date Chyna and has a three year-old son with her, which became a sticking point once the engagement was announced. Twitter got pretty savage, prompting Tyga to craft a response.

"Only an evil heart would direct negativity at a child & make fun of him for being in a situation that is out of his control," Tyga tweeted. "When u been blessed how I've been, & create some1 u love unconditional, u'll understand how I feel. Ull want to protect that blessing. Cherish yo own blessings and stop hating mine."

Tyga did have well wishes for the newly engaged couple as well. "It makes me happy to see the mother of my son happy. My only concern in this situation is my son. I want him in happy environments," he wrote. "He's innocent in this. & I want him to feel as much love as possible."

A source close to the Kardashian posse says no one is slated to comment publically on the engagement and that they’re not too happy about it. There have also been rumors that they believe the engagement won’t stick as Rob has always proposed to girlfriends during serious relationships.
