She's the biggest pop star in the world right now. The safety and security will be intense and handled from now until it's over. Whoever made the mistake that injured/killer her would be injured/killed themselves. So while there's a risk, it's more likely that everything would go off without a hitch.
ugh I saw gravity and it freaked me out so bad! space scares me enough as it is, but seeing the movie made it worse. but whatever gaga wants to do, I support it!
