Blac Chyna and Rob Kardashian may be celebrating happy news with speculation rife that they are engaged. Rumours that Kardashian, 29, popped the question were fuelled when Blac Chyna posted a photo of herself on Instagram wearing a large diamond ring on her engagement finger.

In the photo, Blac Chyna, real name Angela White, can be seen grabbing Kardashian's face alongside the cryptic caption: "YES !...!...!" The couple, who only began dating in January 2016, are yet to officially confirm the engagement news but fans have been sending congratulatory messages.

The news will also come as a surprise to Kardashian's famous family as it is thought they were sceptical of his relationship with Blac Chyna in light of her turbulent history with his siblings. Blac Chyna, 27, is the former fiancee of Tyga who is now dating Kylie Jenner, Kardashian's younger half-sister. The fashion designer also shares a son with rapper Tyga, three-year-old King Cairo, and was once best friends with Kim Kardashian until Jenner and Tyga's romance began.

Perhaps the rumoured engagement will air on TV with reports claiming Blac Chyna will appear in the forthcoming 12th season of Keeping Up With The Kardashians. A source told HollywoodLife: "Blac is ready to really launch her television career but she wants to do it the right way. She has had failed projects in the past and wants to succeed.

"That is why it is taking her so much time to take the next step. She wants to shoot scenes with Rob for KUWTK but she is having trouble agreeing to terms with the producers and so she hasn't signed a contract yet. Blac has a list of demands the producers aren't willing to agree with."

Blac Chyna has previously hinted at her plans to settle down with the Arthur George sock designer, recently saying in a Snapchat video: "Rob I am not playing with you, I want my eggs cracked. That means I wanna have a baby. I want my name dropped. That means I wanna be married."
