According to reports [1], Rob Kardashian and Blac Chyna are engaged! The controversial couple [2] have only been dating for four months, but it seems they're in it for the long haul. Although Rob's sisters have been cryptic [3] about their approval of their brother's new love, Rob posted a photo [4] of Blac holding a stack of cash with a massive ring [5] on that finger to Instagram on Tuesday. Blac quickly followed suit with a picture on her own account [6] that showed off her new accessory, writing, "YES!...!...!"

Blac's BFF Amber Rose has also come out in support of the newly engaged pair, sharing a sweet message for them on her own Instagram account [7]. "Congratulations to my Family @blacchyna and @robkardashian!!! Pease don't let nothing or no one tear u guys apart!" she wrote. "I never seen my sis so happy and I couldn't be more happy for her!
