Rob Kardashian Adorably Reprimands Blac Chyna’s Son for Cursing

Rob Kardashian is taking his new role of step dad very seriously.

Over the weekend, Blac Chyna shared a video of Kardashian scolding her 3-year-old son with Tyga, King Cairo for cursing. In the caption, Chyna admitted she was hesitant to post the video for fear of what fans and the media would say, but ultimately felt it was too funny not to share. “But Idc it’s too funny my favorite part is when Rob jumps out,” she wrote. “Look at his face. But overall I’m so happy & blessed to have Robert here willing to help teach King right from wrong.

In the video, recorded by King, the three-year-old climbs under the bed and marvels out loud, “Oh shit!” The toddler says the curse word three more times, louder each time before Kardashian finally hears him and asks, “What did you say?”

“Shit!” replies King, before Kardashian tells him,” No, you can’t say that. Don’t say that. That’s a bad word and mommy’s going to get really mad at you.”

“But I can say shit,” King continues before explaining that he’s saying the word because of all of the “uh-scusting” things under the bed.
