Model Blac Chyna, real name Angela White, shocked her followers on social media Tuesday (05Apr16) by sharing a photo of her and Rob as she flaunted her sparkling engagement ring, adding the caption, "YES!...!...!"
Soon after, her best friend Amber Rose congratulated the couple on its engagement, while Blac's mum Tokyo Toni, who had met the Keeping Up with the Kardashians star for the first time days ago, also gushed about the impending wedding on Instagram.
And while Rob's famous siblings have yet to comment on the betrothal, Tyga, who shares a three-year-old son called King with Blac, has opened up on his ex's new relationship status and he slammed critics for directing the attention on their son rather than the engagement news.
"Everybody deserves 2 be happy," Tyga wrote on Twitter. "What some1 does for their happiness is not my concern, as long as it's not interfering wit my happiness. 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's innocent in this. & I want him to feel as much love as possible.
"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. When u been blessed how I've been, & create some1 u love unconditional, u'll (sic) understand how I feel. U'll want to protect that blessing. Cherish yo own blessings and stop hating mine."
Tyga and Blac dated for three years before splitting in 2014.
Blac and Rob's romance has been controversial ever since they began dating in January (16). Blac was previously close friends with Kim Kardashian, while Tyga is currently dating Rob's youngest half-sister Kylie Jenner. In addition, Blac's best friend Amber enjoyed a romance with Kim's husband, Kanye West for two years until their break-up in 2010. Kanye and Kim wed in 2014.
As the engagement news broke, Tyga reportedly jetted off to Vail, Colorado to join the rest of the Kardashian clan for a family getaway, according to TMZ.com.
As for Blac, her representative tells Us Weekly she is planning to legally change her name to become Angela Kardashian.
"She was very excited and loves the ring. She's happy with him and very happy,” her rep tells the publication.
