Kate Hudson's older brother Oliver got straight to the point with his Father’s Day Instagram post and added a nasty message directed towards their estranged father, Bill Hudson.
While most celebs happily wished their dads a Happy Father's Day on social media, it wasn't the case for Oliver.
"Happy abandonment day @katehudson," the 38-year-old captioned the childhood pic of him with his estranged father and little sister Kate.

Oliver and Kate’s mom, Goldie Hawn, divorced Bill in 1980. The 36-year-old actress and her brother were subsequently raised by mom Goldie Hawn and her longtime partner Kurt Russell, whom they've considered to be their real dad.

In an interview in 2000, Kate made it clear that she does not want to do anything with her biological father.
She claimed the he 'doesn't know me from a hole in the wall.'
'But I don't care. I have a dad. The bottom line is, you call your kids on their f****** birthday. I'm glad I had a dad who was there on my birthday,' she added.
The 'You, Me and Dupree' actress chose to pay tribute to Kurt on Sunday.
"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."

The siblings also posted loving notes as a tribute to Russell on his 64th birthday on St. Patrick's Day in 2015.
In honor of her mom's partner of more than 30 years, Hudson posted a sweet picture of the man she calls her dad on Instagram.
She captioned a long, heart-warming message, showing her love for the actor.
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."
