Katie, 36, has said that the Paralympian - who has been jailed for five years - messaged her on Twitter throughout his court case in South Africa.
The former glamour model told The Mirror: "He was direct messaging me during the case. It's weird, isn't it?
"He was saying, 'Thanks for the support,' and stuff. Just all general chit-chat. He was the first one to message me."
Mum-of-five Katie believes Pistorius, 27, decided to get in touch with her after she mentioned him in one of her columns.
Katie had said she would not "judge" the Paralympic athlete from media reports. A month later, Oscar followed the star on Twitter and began messaging her, she claims.
"I wasn't exactly supporting him, but everyone who goes through a trial will be the only one who knows what really happened," she added.
Katie has now reached out to the shamed star and said that she would like to sit down and interview him.
We're not entirely sure if an interview will ever take place, but stranger things have happened when the Pricey is concerned!
It's definitely something we'd like to read in any case.
Meanwhile, Katie has been one busy lady lately as she promotes her new novel, Make My Wish Come True, which is the star's 10th fiction book.
Yesterday, Katie also revealed that fans can expect to see her with new boobs and new hair in her 2015 calendar, which goes on sale two weeks before Christmas.
What will Katie do next? We can't wait to find out!
