Rapper Bow Wow has laughed off reports he clashed with Chris Brown after spitting on the R+B star. The 20-year-old hip-hop star insists reports the two tourmates clashed over the incident are ridiculous. Bow Wow, real name Shad Moss, is alleged to have lost his temper while onstage in Dallas, Texas on Saturday (12Jan08) after experiencing technical problems. Local reports suggested the young rap star stormed offstage shouting at Brown's staff and accusing the singer's management of attempting to sabotage his show. Then, when Brown tried to calm Bow Wow down, the rapper allegedly spat in his face, according to MediaTakeOut.com. But Moss insists he would never disrespect Brown like that. He tells MTV.com, "I just got off the phone with Chris. My mom called me and told me about the rumour. I called him and told him, and he started laughing. We was dying (with laughter). "Anybody who knows me or anybody who's been around me knows I'm not that kind of person... A wise man once taught me, `The most vicious thing you can do is spit on somebody.' "It's just a rumour. It's a big rumour. I would never do that. That's not being a man, that's a sissy act."
