"I told him what the play was," he said of Kardashian. "I told him what he was going to deal with, [like] when I was with [her]. I told him, 'Be careful. I was just with her for three or for years, this is what you're about to deal with.'"
The rapper, who shares 4-year-old son King with Blac Chyna, said the 29-year-old model is "a good person" but comes with "drama."
"She just got a different mentality. She really is a good person at heart, but she's been through a lot in her life and she really didn't have people to help guide her," the star said of his ex-fiancee.
"I knew a [expletive] like him ain't going to be able to handle somebody like her," he added of Kardashian.
"He's coming from a whole different world, you don't know how she move and how she think. When you in love and you don't care what nobody else think, you're just going to love blindly."

Blac Chyna confirmed in an interview with People this week that she's finished with her on-again, off-again relationship with Kardashian.
She obtained a temporary restraining order against the star last week after he shared naked photos of her on Instagram.
"[There's] no turning back," the model told the magazine. "I'm glad I'm relieved of [Rob], but damn, why did I have to get relief in this way?"
Tyga also said on The Breakfast Club that he split from Jenner about "seven months" ago, explaining that public attention to their romance took a toll on their relationship.
"We started off as friends and then we got in a relationship," the rapper said.
"It's ain't a losing thing -- when you make a decision to not be in a relationship with somebody, y'all just make that decision, y'all split ways. I have love for her, but I'm not in love no more."
"I think the main thing was there was a lot of people, a lot of outside influences. She's younger than me, so she's dealing with perception," he explained. "For her, growing up how she grew up, image and perception was everything."
