Rob Kardashian and Blac Chyna are reportedly engaged, just ten weeks after taking their relationship public. Blac Chyna posted a photo of the couple on Instagram -- where she's clearly sporting an engagement ring -- along with the telling caption, “YES !...!…!”

You’d think the rest of the Kardashian clan — known, in part, for their overwhelming (and often very loud) support of each other — would be racing to social media to congratulate the couple. But Twitter proves it not so, as nary a word of well wishes has been spewed forth from a single Kardashian. According to a report from PEOPLE, the family isn’t totally ready to accept the couple's eventual union.

"No one [in his family] is jumping up and down with excitement today," a source told the magazine. "They have made a united decision as a family to not comment on social media yet about Rob's engagement. The news is not shocking, and not totally unexpected.”

The source continued, saying, "There has been a fear that Blac Chyna is manipulating the situation with Rob. That he is getting himself into a situation that is not ideal for him. Blac Chyna has been great as kind of a rebound. As someone that got Rob out of a dark place, that helped him get motivated and healthy again. Let's just be honest, no one is really hoping for a marriage to happen."

PEOPLE also reports that Rob has been in touch with matriarch and momager Kris Jenner, but the decision to stay silent about the announcement has been embraced by the rest of the family.

Blac Chyna’s rep, meanwhile, told the magazine she was elated about the proposal (which took place at her home), and she plans to go by her birth name for the wedding: “She was more than excited, she was thrilled, just super happy...She’s soon to be Angela Kardashian. She’s ecstatic."
