It went up on a Tuesday! Socialite Blac Chyna shocked the world when she posted a photo of her new engagement ring on Instagram. Rob Kardashian proposed to the former stripper-turned-businesswoman on Monday evening. Yes, he bent down on one knee and surprised Blac Chyna with a 7 carat diamond worth $325,000! Chyna’s bestie, Amber Rose, took to Instagram to congratulate the happy couple. However, the Kardashians aren’t rushing to do the same. Reports state that the Kardashian clan is not too happy with the quick engagement. Apparently, they feel as though Rob has a habit of “popping the question” and has done so with ex-girlfriends (i.e. Rita Ora and Adrienne Bailon). The family believes this was too soon for him and that Rob and Black Chyna will not last at all. Nevertheless, congrats to ChyRo! Photos: Instagram/Snapchat
