The rather raunchy mum has been super excited and supportive of Blac's relationship with the reality star, and this photo has her stamp of approval written all over it.
Hunter shared the cute snap, which showed a smiling Rob hugging Blac and Hunter, on both of his sides, as she revealed the adorable nickname she uses in reference to the couple.
She shared the photo with the caption:
"Me and the Chyrobians."
Even more curious, is the ring emoji that has been used frequently on Blac's posts in relation to Rob, constantly hinting at a proposal in the works or an impending wedding.
In the end, Hunter seems genuinely happy for Blac even though she might be less thrilled about the other members of the Kardashian family, with whom she has frequently clashed.
