The big announcement of Blac Chyna and Rob Kardashian getting engaged has made Blac Chyna's ex, Tyga, visibly happy.

The 26-year-old American rapper, who is dating Rob Kardashian's younger sister Kylie Jenner, took to social media to post some pleasing tweets about the newly engaged couple. Tyga and Chyna, who met at the set of music video in 2011, got engaged in 2012 after the birth of their son, King Cairo. The duo split in 2014 followed by Tyga and Kylie's open affair.

The 'Make it Nasty' hit maker, who took to Twitter to show his happy self, revealed in one of his tweets that he is happy to see the mother of his son getting engaged. He also wrote that he is prominently concerned about his son, King Cairo, whom he wants to be in a positive environment.

Meanwhile, after the engagement news broke, twiterrati went a bit nasty and started posting some unreasonable tweets about Chyna and her son King Cairo. As the family tree involving Rob, Chyna, Tyga, Kylie and King Cairo is a little complicated, people on the social media pointed many fingers on the alleged relationships.

One of the obnoxious tweets read, "So chyna gunna marry Rob. Tyga datin Kylie. King Cairos mom and dad double as his aunt and uncle. ...king Cairo is hamlet."

Getting to know about the unpleasant tweets about his son, American rapper Tyga went on with some tweets, lashing out at the haters.

"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 wrote in one of his 'giving back' tweets.
