The feud between on-again-off-again friends Floyd Mayweather and 50 Cent has escalated immensely in the past few weeks. After 50 challenged the undefeated boxer to read a full page from a Harry Potter book for $750,000, the noise from Mayweather's camp remained somewhat faint. According to the latest episode of All Access, Mayweather tells 50 to put more money up and questions the relevance of his music career.

A fan asked Mayweather how he felt about 50 Cent and his $750 thousand wager and this is how the conversation went down:

Fan: "Hey Mayweather, I heard 50 Cent challenged you to $750 thousand."

Mayweather: "That's all he challenged me?" Mayweather yelled bacat the fan. "He gotta raise the stakes."

Mayweather: "Does he still make music?" asked Mayweather. "I ain't heard him in awhile."
