The pop star was performing her hit single `Just Dance` on her `Monster Ball` world tour in Washington on 07.09.10 when she noticed an altercation break out between two people in front of the stage and quickly halted the music. She said: "Stop fighting. Do not fight at this show." To cheers from the audience, Gaga then asked: "Is she ok? Are they both ok? I don`t know who hit who. "I`m sorry. I just don`t want you to fight. This is all about love and happiness. Only fake monster fighting." Gaga - real name Stefani Germanotta - didn`t immediately restart the show, instead indulging in some banter with her fans. Striking a pose and gyrating around the stage the 24-year-old singer asked: "Do you think I`m sexy? I think you`re sexy. "I wasn`t very cool when I was in high school, I used to get made fun of all the time so sometimes I really abuse this part of this show." The singer then revealed that she hates people to tell her the truth. She said: "Does everyone know what I hate more than anything? I hate the truth, in fact I hate the truth so much I prefer a giant dose of bulls**t any day."
