Rob Kardashian and his fiancée Blac Chyna might be in a celebratory mood, but the rest of the family is just waiting for the entire thing to crash down to earth.
That’s the bedrock of a new report by TMZ, quoting multiple family sources.
Rob proposed to his girlfriend of two months on Monday, shocking not only millions worldwide but his immediate family as well. So far, Tyga, his sister Kylie’s boyfriend and father to Chyna’s son, is the only immediate family member to have congratulated him.
And TMZ has the reason for that reluctance, besides the ladies’ disdain for Chyna. They believe Rob is a serial proposer, who gets all mushy in a new relationship and proposes too quickly, and it never ends well.
They say it happened with Adrienne Bailon and Rita Ora.
TMZ writes…

The Kardashian family is offended Rob never gave them a heads-up before getting engaged, but they’re not that upset, because they think he’s just a serial proposer and this one won’t stick … and we’re getting this from sources connected with Rob himself.
We’re told the Kardashians have heard Rob proclaim his undying love many times before. Our sources say the Kardashians have heard Rob gushing about former GFs Rita Ora and Adrienne Bailon — and even told his family he proposed to both.
We’re told the feeling is that Rob just gets smitten and goes from first date to bended knee at warp speed, and it never works out.

Guess time will tell who’s right with this one.
