New Hills Photos! Heidi, LC, Whit And Audrina Shine In White

Remember those behind-the-scenes photos of the Hills gals getting ready and admiring the view in their best -- and brightest! -- Summer frocks?

Check out these angelic pics of Heidi, Lauren, Whitney and Audrina dressed head-to-toe in fairy tale white...

...then visit the new Season 4 flipbook to see the girls ditch the ephemeral whites...and vamp it up in little black dresses.
