The 42-year-old entrepreneur dismissed reports that Kardashian and West are headed for a split in an interview with E! News at the DailyMail.com holiday party Wednesday.
"I just FaceTimed with Kim and Kanye and everyone's talking about some divorce rumors," Cheban said. "I was laughing because I didn't hear that all day, and I guess everybody else apparently here did. It's so funny to me because it's so not true."
"I don't know where people come up with stories, but it's literally hysterical. Jennifer Aniston has also been pregnant like 1,000 times, so it's kind of a joke," he added.
"They're in good spirits. I don't want to talk much about them, just because it's not my business, but I did have to say that the divorcing was kind of hysterical," the star said. "When I heard that I literally burst out laughing ... There's no divorce."
Us Weekly had reported earlier in the day that Kardashian "wants a divorce" from West. Sources said the 36-year-old reality star is "trying to build a case for full custody" of the couple's two children before she files to end the marriage.
"It will take some time before she can do anything, but she doesn't want to stay married," an insider said.
Kardashian and West married in 2014, and share 3-year-old daughter North and 1-year-old son Saint. The reality star has kept out of the spotlight since being robbed at gunpoint Oct. 2 in Paris, while West was released from the hospital Nov. 30 after more than a week-long stay for exhaustion.
"Kanye and Kim had a stressful few months," a source told People on Tuesday. "It's been a tense time. But Kim is happy he's getting help."
"[Kim] has been] very focused on being supportive and managing the crisis that is going on," the insider added. "She is super focused on him. [She's been] the dutiful, responsible, loving spouse that one would expect."
