"Happy abandonment day... @katehudson," the "Nashville" star captioned a vintage pic with his birth father.
In the photo, a young Oliver stands with sister Kate Hudson as they pose with their estranged father actor and musician Bill Hudson.
The "Rules of Engagement" alum and the actress have been vocal in the past about their biological dad and his absence in their lives. Both have said that they consider mom Goldie Hawn's long time partner Kurt Russell their true father figure.
"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," Oliver said of Kurt on the actor's birthday earlier this year. "I look up to you and always will."

"Pa, just simply..... Thank you Happy Fathers Day I love you to the moon and back. #HappyFathersDay," she said of the pic.
