TMZ Live Mayweather's KO Definitely Cheap ... but Fair

Did Floyd Mayweather sucker punch Victor Ortiz? Yes. Was Ortiz stupid for not defending himself? Absolutely. Is it possible for Harvey "I'm a Lawyer" Levin to debate BOXING with sports guru Fred Roggin? Damn straight.

And, can dogs die from a broken heart? "Dog Whisperer" Cesar Millan calls in to explain why the concept isn't so far-fetched. Plus, restaurant horror stories that make Christina Milian's ABC gum incident look appetizing.
