They spoke out at their first television interview on Thursday.
The twins Georgia and Patterson Inman, 16, recounted how they endured years of abuse by caregivers hired by their meth-addicted Father Walter 'Skipper' Inman Jr, nephew of Doris Duke.
They lived with their father until he died of an over dose in 2010, they now live with their mother, Daisha and will inherit part of the Duke fortune when they turn 21.
Their stories of abuse contrast sharply with the way they lived their lives - Taking Diamonds to school for show-and- tell, holidaying in Fiji, keeping exotic pets like camels and chimps.
'People see this luxurious life but at the same time we were living in hell' Patterson told Dr. Phil in the exclusive interview,, that aired on Thursday.
The alleged abuse began when their parents divorced and their father , who received an estimated $90,000 monthly allowance gained custody of them in 2000, when the twins were two years old..
In the years to follow they were burned with boiling water made to slay in a feces lined basement and made to live for days without food and locked behind dead bolted doors, they told Dr. Phil.
Georgia recounted a putrid stink that permeated their Wyoming mansion and how they were fed stale food in a rat-infested home where babysitters would come and go.
They would play Russian Roulette with us' Georgia said of their caretakers, 'They thought it was funny, they'd load the gun spin it and shoot at me and my brother'.
She claimed that they also tied her feet, taped her mouth and made her eat her own sick from the carpet, she got mad when i couldn't eat it, she said of one of the paid nannies.
Her brother recalls another time the nannies made him eat his own feces.
He said they feed him the feces pretending it was food.
The abuse did not come from only the caregivers, they said their Father was also one of them
But Georgia said the abuse didn't just come at the hands of their caretakers.
"While Patterson has fond memories of his father - blowing up vehicles, collecting guns and speaking to hookers aboard boats in New Zealand - Georgia's thoughts are not so happy.
She told Dr Phil that her father also beat them, punching them in their faces and heads. Her brother refused to speak about the claims.
'He would pick me up by the ankle and just drop me on my head because he wanted to make me stupid,' Georgia claimed. 'He used to slice my feet up with knives.'
They both claimed they saw their father overdose regularly and that adults had told them to revive him by splashing cold water on his face.
