Jennifer Hudson has been sober her entire life.
The revelation came during an interview Thursday night on the E! talk show "Chelsea Lately," where the 32-year-old singer-actress discussed her upcoming film, "The Inevitable Defeat of Mister & Pete," in which she plays a heroin addict.
"I've never done anything, so that was hard to play this role," Hudson said. "I've never had a drink in my life. I'm sober. I'm like, 'Okay, 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."

After joking that heroin was "the only drug I've never tried," the show's host, comedian Chelsea Handler, was taken aback by Hudson's sober admission.
"What do you mean you've never had a drink? "What are you waiting for?" Handler asked.
"I don't know. I've never been interested. Nobody ever believes it," Hudson responded. "When I got this role, I was like, 'Oh my god, what am I gonna do? What am I gonna pull from to play the role?'"
Hudson told Handler that in order to prepare for the role she met with ex-addicts at a rehabilitation center.
"They took me through each and every step of what it's like, how you get addicted to drugs and what it feels like when you are high," she recalled.
After finishing as a finalist in the third season of "American Idol," Hudson was propelled into the spotlight as a result of her 2006 film debut in "Dreamgirls," which follows a trio of black female soul singers in the early 1960s.
Hudson won an Academy Award for Best Supporting Actress, as well as a Golden Globe Award, a BAFTA Award, an NAACP Image Award and a Screen Actors Guild Award as a result of her role in the film.
Hudson is also a Grammy Award-winning singer, and is a current a spokeswoman for Weight Watchers, having lost 80 pounds. She subsequently published her autobiography, "I Got This: How I Changed My Ways and Lost What Weighed Me Down."
A strident supporter of President Barack Obama, the Chicago-born Hudson campaigned for the president in both 2008 and 2012, and is presently starring in a TV campaign to promote Obamacare
