The siblings were eventually raised by the Oscar-winning actress and her partner Kurt Russell, who became an integral part of their lives and who they affectionately refer to as "Pa."

For a long time after Goldie and Bill's separation, the relationship between the dad and his children was strained. Since then, however, it has improved, with Oliver even acknowledging in 2018 that he had exchanged "some texts" with his estranged father.

Kate didn't keep in touch as much, however she did say in a 2016 interview with Howard Stern: "I really do recognize whatever those issues are, it’s just something that he has to live with, and that must be painful for him, so I forgive him."

Bill has three children from other relationships, while their Pa Kurt has a son, Boston, and the Hudson siblings mused over them in a recent episode of their podcast Sibling Revelry.

Oliver, meanwhile, did pay homage to his biological father on Father's Day in 2021, sharing an image of him alongside one of Kurt and one, comically enough, of Warren Beatty.

He wrote: "It doesn't really matter which one of these men is my father. My Pa stepped in when I was 6 and made the man I am today.
