After they posted a pair of nastily-captioned photographs to Instagram on Father’s Day, Bill Hudson, father of Kate and Oliver Hudson, disowned his two eldest children, telling the Daily Mail, “I no longer recognize Oliver and Kate as my own.” Yikes!

On Father’s Day, Oliver Hudson—Bill’s first-born child with Goldie Hawn—posted a photograph of him, his sister Kate, and their father to Instagram with the caption, “Happy abandonment day.”

Kate, meanwhile, posted a photograph of herself with Kurt Russell, with whom Hawn carried on a 30-year romance, with the caption, “Pa, just simply... thank you. Happy Father’s Day. I love you to the moon and back.”

Bill Hudson accused Hawn of poisoning his children against him:

‘When we split up, she never had a bad word to say about me,’ he says. ‘But when Kurt came on the scene, the narrative changed and I became the big, bad wolf. I would say to her “Goldie, why are you trashing me and saying I’m an absent father when it’s simply not the case?” and she’d laugh and go “Oh Bill, you know it makes for a better story”.’

Eventually, Bill says, the fiction became fact as first Kate, now 36, and then Oliver, 38, ‘drifted away’ from him and rejected his repeated pleas to remain part of their lives. He lays the blame at Goldie’s door. I believe the drip, drip, drip of poison which started when they were kids finally took hold,’ he says. ‘Goldie wanted to create this myth of a perfect family with Kurt and she wanted me out.’

Now, he said, he wishes to “break all ties” with his two eldest children. “I had five birth children but I now consider myself a father of three,” Hudson said. “I no longer recognize Oliver and Kate as my own.”

“I would ask them to stop using the Hudson name. They are no longer a part of my life. Oliver’s Instagram post was a malicious, vicious, premeditated attack. He is dead to me now. As is Kate. I am mourning their loss even though they are still walking this earth.”
