27 Dresses.

I saw the preview for this movie and totally laughed!  If you haven't heard of it already, it's with Katherine Heigl who was so funny in Knocked Up! They are playing off the "always a bridesmaid, never a bride" theme, I think it could be really funny and tons of us can relate! 
This has ladies nite written all over it. So, get dressed up,  head out for cocktails, and then see the movie!  (cocktails will ease the pain if it's a bomb.)

Check out the trailer...
