Naomi Watts looked fabulous last night at the premiere of Eastern Promises at the London Film Festival. She was joined by her costar Vincent Cassel, Colin Firth and Elle Macpherson. Obviously the balance of working and being a new mom is suiting her. At the Calvin Klein party the other night, Naomi revealed her secrets to looking good while still working off the baby weight. She said, "I've got a lot of solid undergarments. Good classic lines can also help cheer up an out of shape body." We have a feeling there may be more to this story than just flattering designs and underwear, but whatever she is doing, it's working.

Lots more pics of the premiere so just read more
