Anne Hathaway, on how she managed to quit smoking

The 32-year-old Oscar winner told The New York Times Magazine  she started smoking while portraying a drug addict in Rachel's Getting Married (2008).

"I got hooked for a few years," she said.

Hathaway stayed away from cigarettes for four years, before taking them up again when she was producing and starring in her latest film, Song One, which premiered at the Hamptons International Film Festival last October.

"It's easy to romanticise it when you haven't done it in a while, but it's actually pretty disgusting," she said.

Although she has quit smoking altogether, Hathaway said she doesn't judge smokers who swap to e-cigarettes.

"I don't judge the vape," she said.

"I know some people who used to be three-pack-a-day smokers, and I'd much prefer them having the vape."

Hathaway also revealed she is planning to give up a second unhealthy vice: alcohol.

But don't jump to any conclusions.

While she has been married to fellow actor Adam Shulman since 2012, she was quick to point out that her new year's resolution "has nothing to do with pregnancy".

"It's just because why not."

Song One is being rolled out in limited release internationally  early this year.
