RadarOnline.com has exclusively learned that Khloe Kardashian has been pouring her heart out to her rumored birth father, O.J. Simpson, with the pair regularly exchanging letters while he languishes behind bars.
"This has been going on for years, ever since Khloe first confronted O.J. about the paternity rumors," an insider told Radar.
Despite the 32-year-old reality star's desperation to know the truth of whether or not Simpson, 69, really is her father, the former football great isn't willing to provide her with any answers — yet.
"His whole thing is to wait until he's released until agreeing to a DNA test," said the insider.
As Radar reported, Simpson is serving time in a Nevada prison after he was charged for armed robbery, kidnapping and other charges following an attempt to steal sports memorabilia he said rightfully belong to him.
In the meantime, a second source confirmed to Radar that Kardashian isn't the only one desperate for paternity answers: Kris Jenner, 60, "has been begging O.J. to have a DNA test for years."
But until that happens, Simpson is busy bonding with Kardashian and forming a deeper friendship, noted the insider.
Surprisingly, "Khloe's been open to that for whatever reason," said the insider. "Kris knows they've exchanged the occasional letter, but she would flip out if she knew just how strong their bond's become."
