During their talk, the new couple discussed people's opinion about their coupling, Ramadan and Montana's relationship with his pseudo mother-in-law Kris Jenner.
"People are going to comment no matter what," Kardashian said of her relationship to the rapper. "If I like [Montana], no one else should care, they're not [expletive] him. So why do they care?"
For those who do care, Kardashian shared that her beau is currently observing Ramadan, an annual month of fasting in the Islamic calendar.
"That's no eating, no drinking, no smoking," she said.
"Wait -- there's no sex! How's that been?" asked host Angie Martinez.
"So fun," the reality star joked. "That's why he's wearing all white. He's so pure and holy, he's virginal."
Asked if she's been teasing him, Kardashian replied "everyday."
As for whether or not Montana will be featured in the new season of Keeping Up With the Kardashians, the rapper said he's been called to appear a few times and that Kanye West will be there too.
Montana later added that he was "best friends" with Kardashian's mother Kris Jenner and that the two often "drink together."
