'Twilight' new moon, anyone?

The latest Twilight movie opens in just 18 days -- on November 20.

If you're looking for a little eye candy to tide you over 'til then, check out this pic of Kellan Lutz and Ashley Greene, who got into the Halloween spirit at Veuve Clicquot's Halloween bash at TAO Las Vegas.

Kellan Lutz dressed as Batman, while Ashley Greene wore some sort of sexy peacock ensemble.

No word on what Robert Pattinson and Kristen Stewart wore, or if they event dressed up at all.
