Mitch Winehouse made the revelation on Australian television as he hit out at the makers of a biopic on his tragic daughter for their presentation of her as a loner, despite the fact that she was engaged at the time to British film director Reg Traviss.
Mr Winehouse told Channel Seven’s Weekend Sunrise show: “She was with Reg, they were going to get married.
“I shouldn’t tell you this but she thought she was pregnant at some stage.
“To give the impression that she was on her own is frankly criminal.”
Mr Winehouse, who has been critical of Amy, the recent film made by director Asif Kapadia, has said he is working with her former fiance on a new documentary.
His 27-year-old daughter died of alcohol poisoning in 2011 after a public struggle with drink and drugs.
She enjoyed commercial success with songs ‘Rehab’ and ‘Back To Black’ in her short career.
