Senator Derryn Hinch has fallen off the wagon, according to his ex-girlfriend.
36-year-old Natasha Chadwick outed her former flame on Twitter for his drinking habits – five years after being given a lifesaving liver transplant.
'Derryn Hinch has been back on booze 12+ months. So much for respecting organ donors gift of life. Fave wine, cheap Gossips. No loyalty,' she posted on Sunday.
Derryn required a transplant after his alcohol use caused him to develop advanced cirrhosis and liver cancer.
According to The Herald Sun, the former shock jock admits he has enjoyed the odd drink since receiving his transplant, but insists that they were watered down and he sought the permission from his surgeon.
'I've had the odd glass of wine, perhaps one-third wine and two-thirds water, with Natasha at birthdays and at events like Christmas,' the 72-year-old admitted.
However, Natasha claims they only recently shared a glass of wine and she had seen him drink a light beer on the night of his maiden speech, where he humbly acknowledged the sacrifice his donor's had family made to save his life.
'Since then he's been back on it regularly, starting the day with non-alcoholic beer for breakfast, then moving to his Edenvale non-alcoholic wine and then moving on to harder stuff,' a source told the Herald Sun.
'He's even spent an afternoon at a pub in Redfern in Sydney and come home stinking of alcohol,' they added.
