Comedian Daniel Tosh alleged on his podcast that Kylie, 26, had filmed a scene revealing she was pregnant with Chalamet's child for an episode of The Kardashians at a grocery store in Malibu.
A source tells DailyMail.com the claims are '100% false' suggesting that the comedian's unfounded remarks were a ploy to gain attention to his podcast.
Tosh, 48, alleged he was told the information by an employee who worked at the grocery store after he asked why they had recently closed for the day.
Tosh said on his podcast, the Tosh Show: 'Here's something crazy. I went to the grocery store in Malibu, and I was talking to an employee there... I try to avoid it but I was talking to this guy, and I said, "Why were you guys closed yesterday?" He goes, "Well, I’m not supposed to discuss it, but Keeping Up With the Kardashians, the show, was filming their season finale here yesterday."

'Spoiler alert, this is for the upcoming season of the show. This is the big season finale. This random grocery store person is telling me that they rented out the entire store, shut it down and then, they acted like they were grocery shopping.
'This was the scene that apparently happened: that Kylie reveals that she’s pregnant again with, wait for it, Timothée’s kid. Holy moly, what a bombshell,' he said.
Tosh acknowledged what he was told may not be true: 'This might not be true. I am not verifying anything. This is what an employee at a grocery store in Malibu told me.'

While Kylie has been working hard promoting her new line of Vodka sodas, Sprinter, her boyfriend has been in New York filming his new Bob Dylan musical drama, Bob Dylan, A Complete Unknown.
Chalamet plays the iconic folk singer himself and has been spotted on the set as of late.
Directed by James Mangold, who's working from a screenplay he co-wrote with Jay Cocks, the filmmaker maintains the 'movie isn't really a Bob Dylan biopic', due to it being focused on a period of the singer-songwriter's life, according to Rolling Stone.
