The very lovely and charming Rachel Weisz was on David Letterman last night where she talked about her son’s fascination with firemen and women’s breasts.  Here is a little snippet of her interview with him.  She is positively stunning.

She was on to promote ‘The Lovely Bones‘ which opens in theatres January 15, 2010.
