Kate posted a sweet Instagram message to her stepfather Sunday, while her brother called out their biological father, Bill Hudson, writing, "Happy abandonment day"
“Pa, just simply…Thank you,” Kate wrote alongside a smiling, black-and-white photo of her with Russell, whom she calls “Pa.” “Happy Fathers Day I love you to the moon and back.”
Meanwhile, Oliver posted “Happy abandonment day” on Instagram alongside a childhood photo of him and Kate with their biological father.
It is no secret that the siblings consider Russell – who has been their mother Goldie Hawn‘s partner for more than 30 years – to be their father.
The siblings posted loving notes as a tribute to Russell on his 64th birthday on St. Patrick’s Day in 2015.
“Happy Birthday to the most dependable, strong, authentic, loving and fun Dad! I love you!” Kate wrote last year. “This is a man who made his family his number one priority his whole life. Never missed a school play, a soccer game, a hockey game, a dance recital and the list goes on and on.”
Continued the Rock the Kasbah actress: “No matter what he was doing in his busy life, he always showed up. Not because he had to but because there was no other place on earth he would rather be than with his family. We felt the purity of that our whole childhood and my gratitude for his love is immeasurable. Happy Birthday Pa.”
Her brother, meanwhile, wrote: “Before you came into my life, I was only potential and you made me, forced me, to find my confidence, my independence and strive for the elusive fearlessness that you so matter of factly possess…I look up to you and always will.”
