Rob Kardashian Lovingly Scolds Blac Chyna's Son King for His Potty Mouth

Kids say the darndest things!

Rob Kardashian is poised and ready to become a fantastic father, as an absolutely precious Instagram video shared by Blac Chyna revealed the E! reality star is busy practicing his parenting skills with her 3-year-old son King Cairo.

In the video, which Chyna wrote she was initially “hesitant” to post, Rob and King are spending some quality time together when the toddler does exactly what every other kid his age has done when they’re parents aren’t looking. 

“S–t!” King says, to which Kardashian immediately responds, “What did you say?” 

“I said, ‘s–t!'” he replies in a hilarious matter of fact tone. 

Leave it to the father-to-be to step in with some wise words, as he tells King, “You can’t say that. Don’t say that. That’s a bad word. Mommy’s going to get really mad at you.” 

And Blac has no qualms about her fiancée stepping in to a father figure role for her first child with rapper Tyga, as she captioned the video, “But overall I’m so happy & blessed to have Robert here willing to help teach King right from wrong.” 

The engaged couple is currently gearing up for the premiere of their new reality series Rob & Chyna. During a recent Facebook Live chat, Chyna confirmed that we’ll see King Cairo on the show.

“You guy are going to definitely see King on Rob & Chyna because he is a part of our lives,” she explained. “That’s my baby, it’s going to be his.” Well, it looks like Rob is already off to a great start. 

Watch the series premiere of Rob & Chyna Sunday, Sept. 11 at 9 p.m., only on E!
