Remember that old proverb, "the enemy of your enemy is your friend"? Well, Tyga and Rob Kardashian seem to have taken it to heart as both of them feud with their mutual ex and baby mother, Blac Chyna. 
This unholy alliance is reportedly worrying a member of Rob's family, who is begging Rob to take sides with his baby's mother, not his sister's man.

Interestingly, Chyna's biggest ally in the Kardashian family these days seems to be her almost mother-in-law, Kris Jenner.

And insider close to the situation told Hollywood Life that Kris can't believe she's still stuck with Tyga, even though her daughter Kylie is reportedly trying to move on.
"Kris is warning Rob not to be palling around with Tyga," the source said. "She's doing what she can to convince Rob that he needs to support his child's mother, Blac Chyna, and sort out his issues with her. Rob can't play games with his family, and Kris is worried that Tyga will get in his head." The source adds, "Kris fears Tyga's issues with Chyna will become Rob's problems, too, so she's doing everything she can to keep Rob away from Tyga's influence."

These reports prove that while Kris certainly has her problems with Chyna, her disdain for Tyga trumps all.

While Rob and Chyna may not get back together anytime soon, Kris clearly hopes that their problems don't affect her or her son's relationship with baby Dream.
