Hollywood beauty Penelope Cruz is such a fan of karaoke, she bullies her friends into performing with her whenever they drop by. The Vanilla Sky actress loves to indulge her singing passion, but admits it's sometimes hard to garner the same enthusiasm from her pals. She says, "I have Karaoke at home. All my friends have to do it but I don't tell them before otherwise they won't come." Cruz sings in her latest film VOLVER.
