I'm not sure if this is a mini-dress or if Leighton forgot to put on some pants this morning. I'm hoping it's the latter, because that's much hotter than a dress that goes up past her crotch. ... ... wait, wait no. I take that back. The dress is hotter.
This is supposedly at a pre-Oscar event, but usually those aren't so slutty. The Academy Awards are usually full of elegance and history. Not Leighton's naughty bits and hooker-fashion.
