Actress Penelope Cruz has revealed her obsession for karaoke parties. The Oscar nominee said that guests at her parties are quite inhibited by the idea at first, they later land up fighting for a chance to grab the microphone. "I have a machine at home. Everyone arrives saying they're not going to sing, but everybody sings. They all say, ‘I'm too cool for karaoke,' and then they are fighting for the microphone," she was quoted as saying.
