6. JULIANNE MOORE
What makes this 50-year-old actress so sexy is that she looks as if she can still pull off roles like the one she had in Boogie Nights (i.e., porn star), and, what's even better is that she still does. In the past two years, Moore has played a lesbian having an affair with a man in The Kids Are All Right and as a straight woman having an affair with a lesbian in Chloe, both in the nude. And our eyes didn't burn, either. Well, they sort of did, but in the best ways possible.
