The heat is on. WBA welterweight champion Shane Mosley has fired back at Floyd Mayweather Jr.'s recent verbal attacks. During a recent appearance on ESPN Radio, Mosley took aim at Mayweather's constant comments about his physical appearance. Mosley faces Mayweather on May 1 at the MGM Grand in Las Vegas.

"He wants to talk about my suit. You know? He's talking about the curls in my hair, and if I'm getting a nose job, I mean, is he funny? Is he gay or something? You know, all of these different things about my personal stuff, and I'm like, 'Wow, he's reading into it that much?' So, I mean, you've got to watch out. There's different things that don't sound right. You know?" - Mosley said.

Mosley is also tired of Mayweather always bringing up his past use of performance enhancing drugs. Prior to the 2003 rematch with Oscar De La Hoya, Mosley was using drugs from the BALCO Lab. Mosley has always claimed that Victor Conte, the BALCO Lab Founder, misinformed him about the dangerous and illegal nature of the drugs.

Shane has turned the tables on Mayweather, throwing some steroid fire back at Floyd and his beefed-up security team.

"What's weird to me is that everybody on his whole team, all of his security guards, they look like they're on steroids. They all look like they're on 'roids, and I don't understand it. I mean, why does he [Mayweather] keep saying, 'Steroids, steroids, steroids,'" said Mosley.

"And, you know, I notice that Floyd always shaves his head, all of the time. His head is shaved. His head is starting to look a little bigger. You know? Maybe, I mean, he has all of these people around him that's on steroids, maybe he dibbles and dabbles a little bit. The guy that keeps talking. You know, the guys that usually talk about it all of the time, 'Oh, steroids, steroids, steroids, oh, oh.' They're usually the ones on it."

"I'm not accusing him, I said, 'Usually.' I didn't accuse anybody of anything. Like I said, the guys are going in the gym, and they're doing weights and all of that, they look like they're on roids, for real. You've got that type of company around you all the time, then nine times out of 10, you're doing something."
