Blac Chyna doesn't mess around when it comes to her son, King Cairo Stevenson — and she doesn't like that he's hanging around Kylie Jenner!

According to Radar Online, the 27-year-old former stripper has told Tyga, 25, to "keep Kylie away" from their two-year-old.

“Blac told Tyga that she does not want her son to even be around Kylie, but there is nothing that she can really do to stop this,” a source tells the outlet.

Although it's no secret the two girls are not fond of each other from their social media wars, we aren't exactly sure what provoked her to take it to the next level. Perhaps she didn't like seeing her son hit Disneyland for North West's second birthday? Or the fact her ex is with a 17-year-old?

The source continues, “Tyga pretty much raises King Cairo and Blac Chyna is only a part-time mother. Kylie has taken on a role of second mother to King, but she is in no way prepared to handle the role.”

Hopefully they can all come to an amicable agreement sooner than later…
