Jennifer Hudson has never tried alcohol.

Jennifer made her surprising revelation during an appearance on talk show 'Chelsea Lately' on which she was quizzed about her role as a heroin-addicted mother who is arrested leaving her two sons to fend for themselves in harrowing new drama film

'The Inevitable Defeat of Mister & Pete'.

When asked if she has ever personally experimented with drugs by host Chelsea Handler, Jennifer replied: "I've never done anything, so that was hard to play this role. I've never had a drink in my life. I'm sober. I'm like, 'OK, this is new to me.' Normally as an actor, you have things to pull from. I was like, 'I don't know what it's like to feel any of that.' "

Chelsea - who has always been open about her past drug use, dabbling with ecstasy and cocaine - seemed shocked by Jennifer's revelation, asking: "What do you mean you've never had a drink? What are you waiting for?" To which Jennifer replied: "I don't know. I've never been interested. Nobody ever believes it ... When I got this role, I was like, 'Oh my god, what am I going to do? What am I going to pull from to play the role?" As she couldn't draw on personal experience, the Oscar winner - who has three-year-old son David Jr. with her fiancé, WWE Superstar David Otunga - researched the tough part by visiting ex-addicts at a rehab centre. She said: "The stories that I heard [were] like unbelievable."
