This week Rob Kardashain's baby mama, former stripper Blac Chyna, was caught on video using their daughter's stroller as a weapon during a fight at Six Flags Magic Mountain [click here if you missed that].
Turns out none of the Kardashians are surprised by Blac Chyna's behavior...
Kardashian klan insiders tell E! News
"Nobody is surprised to see what happened. They are just glad Dream was not in the stroller and was safe. It's concerning that Chyna behaves this way with Dream around, but this is typical Chyna behavior."
"It's a shame that she can lose control of herself and rage so easily. The family hopes that she will be better for Dream and will learn from this."
