It was disrespectful because she wasn't invited to come on the stage. She didn't have to scream anything or throw condoms Jay Z and Alicia were asked to do the show. They prepped for it, worked hard, and then half way through their performance some chick neither are cool with came on stage and made it about her. Jay Z even made fun of her a little on stage trying to get her to sit back down but she refused. Then at the end she poses like she did something, lol.

I'm sorry it got so ugly for her but she did deserve some ridicule for doing that.
