After all the talk going on between Floyd Mayweather and 50 Cent we have finally come to the moment where words and dirty laundry are more than likely not going to be enough to satisfy either man and the first man to show that is Mayweather. Mayweather took to social media last night to challenge 50 Cent to a 12 round fight at the MGM Grand with a special stipulation to the loser. “Enough jokes 50 Cent. Me and you, 12 rounds, MGM Grand, loser pays $12,000,000 cash. Talk the talk but walk the walk kiddo.”
