Hollywood actress Keira Knightley hates attending glitzy parties because she can't talk to strangers, and wishes she was more confident like fellow actress Sienna Miller. The Pirates Of The Caribbean star struggles to make an impression at the star-studded events, and is envious of close friend Miller and her ability to dazzle partygoers. She explains, "I don't like going to parties because I'm terrible at small talk. I look at my friend Sienna Miller and see her really being wonderful and chatting and looking so happy at parties. "I just freeze up and go blank. I get incredibly nervous and start becoming paranoid. I just stand in the corner clutching on to whoever I arrived with."
