Naomi Watts Covers 'Manhattan' December 2012

Naomi Watts looks lovely on the cover of Manhattan magazine‘s December 2012 issue.

Here is what the 44-year-old The Impossible actress had to share with the mag:

On playing Princess Diana in her upcoming film, Diana: “Playing Princess Diana was the hardest thing I’ve done…I wanted to try to embody her and get the essence of her. The film concentrates on [Diana's] love affair with a Pakistani heart surgeon, which I didn’t even know about. That love story ended sadly.”

On her New Year’s resolution: “Life is short! Enjoy it!”

On being queen of the remake and playing historical characters: “There is nothing new out there.”

On why she never married partner, Liev Schreiber: “Marriage? It feels like, why fix it if it ain’t broke?”
