Inside Movies reports on Natalie’s dangerous stunt for tonight’s Oscar ceremony…that of walking across a stage in stilettos.

For her rehearsal, Portman kicked off her casual shoes and strapped on the intimidating, sparkling gold stilettos she’ll be wearing for the show.

Walking across the shiny black stage must have been like tiptoeing across an ice skating rink, but along with her lines, the Black Swan actress got in some practice walking. Before you can look glamorous, you have to be graceful.

We’ll be updating later with photos from the event, and if Natalie hits the red carpet, you can try spot her on Popsugar’s live red carpet feed.
