Tension continue to rise in the Nelly vs. Floyd Mayweather beef, as the "Thanks To My Ex" artist publicly clowned the undefeated boxer on television. Today, Nelly made a guest appearance on the ESPN2 show Highly Questionable, where he was asked questions about his music, the infamous "Tip Drill" video and of course, his beef with Floyd Mayweather.

When asked to discuss the extent of their issues, Nelly denied having any problems with Mayweather, followed by a low-blow diss about his education...or lack there of.

"I think the whole thing is misunderstood. It's kind of hard talking to a guy who hasn't graduated from high school," said Nelly.
