Kim Kardashian’s close friend Jonathan Cheban slams Amber Rose and Blac Chyna for targeting Kylie Jenner and Tyga. Chyna, the former girlfriend of Tyga, and Rose, began a social war with Jenner after the 17-year-old “Keeping Up with the Kardashians” star began dating the rapper.

“Kylie’s young, they’re not. They are bullies,” Cheban told Radar Online, referring to Rose and Chyna. He reportedly admitted that he and Kim were friends with the two. “Both of them are kind of street. They take it to another level and they’re always looking for a fight.”

"I want to bully them back. They're really aggressive. They should at least wait till Kylie is 18,” Cheban, whose website, the Dishh, publishes entertainment news, reportedly said. “I want to show them what it is like. I’m not taking sides. They’re too ghetto, too street. They’re bullies.”

Chyna was reportedly the reason behind Kylie and Tyga’s split last month. Troubles between the two erupted after Chyna posted personal messages of her conversation with Tyga on social media, giving rise to speculation that Tyga, the father of Chyna's 2-year-old son King Cairo, wants her back.

“She’s got sisters to tell her what to do,” Cheban reportedly said, adding that he is not going to give any relationship advice to Kylie. “I’m am just a friend.”

The Kylie-Chyna drama began last month with the Kylie Jenner Lip Challenge. Chyna posted a picture of herself with giant wax lips, taking a shot at the challenge in which several naive teens sucked on shot glasses in an attempt to copy Jenner’s pillow pout -- some of which turned disastrous. Chyna's close friend Rose also slammed Kylie and Tyga in a February interview with Power 105.1 FM's Breakfast Club.

"She's a baby, she needs to go to bed at 7 o'clock and relax. That's ridiculous. [Tyga] should be ashamed of himself. For sure. He has a beautiful woman and a baby and left that for a 16-year-old who just turned 17," Rose reportedly said about Kylie, when asked about the latter's relationship with Tyga. 

Meanwhile, recent reports suggested that Kylie and Tyga were back together after an intimate picnic before Tyga’s concert at California State University in Fullerton last week. The Hollywood Life reported, citing sources, that Tyga was desperate to get Kylie back in his life and had decided to pay $500,000 to Chyna to keep her away from Kylie.
