Kim Kardashian Says Brother Rob Talked About His Imaginary Friends ‘Up Until Last Year’

Kim Kardashian is spilling the beans about one of her brother’s more peculiar quirks.

In a newly-released bonus scene from her recent appearance on “Busy Tonight,” the makeup mogul revealed that Rob Kardashian once counted some fictional pals among his inner circle.

“My brother has – I don’t know if he still does – but he had, for a really long time, two imaginary friends,” she dished to Busy.

When the late-night host asked Kim if she remembered Rob’s friends’ names, she didn’t miss a beat.

“Of course! Pablo and Ronald,” the reality star replied.

“My brother literally has talked about these guys, like, up until last year,” she continued. “There’s one more – I can’t remember his name.”

While Kim may have drawn a blank on her brother’s third pal, “Keeping Up with the Kardashians” superfans will remember that he goes by Cornelius. On a 2017 episode of the reality show, Khloé Kardashian hilariously summoned her bro’s imaginary buddy as a substitute conversational partner after Kim and Kourtney ignored her on a shopping trip.

While Khloé was keen on some bonding time with Cornelius, Rob later admitted that his companion has been less present in his life these days.

“Honestly, I don’t really see him as much anymore,” he told his sister when she recounted her and Corn’s hangout over the phone. “I’m not real comfortable talking to him.”

The Arthur George designer attributed their falling-out to the fact that Cornelius’ “wife died” – which had Khloé in shock.

“What?” she gasped. “Cornelius, why didn’t you tell me that your wife f***ing died?”

While Rob’s trio of fictitious pals may seem unusual, he’s not the only star whose imagination ran wild as a kid.

“I had an imaginary friend,” Busy confessed in response to Kim’s story.

And the name of the “Cougar Town” alum’s childhood pal?

“Dairy Shackson,” she conceded with a laugh.
