Floyd Mayweather's father spoke to Brian Shapiro from "The Vegas Take" on Fox Sports 670 Las Vegas, and addressed 50 Cent making fun of his son online. The elder Mayweather claims that Fif is upset that his son turned his back on their friendship, and thinks the rapper needs to grow up.

"50 Cent seems like he's got a problem since Floyd left him. He's a world known singer and he's acting like a kid."

Earlier this week Fif told Floyd that he would be in Vegas if he wanted to throw down, and Mayweather Sr. thinks the Queens rapper would get dropped in the ring. He adds that 50 wouldn't be talking any more smack after the fight.

"He weighs over 100 pounds more than Floyd. Let him go up against Floyd ... put that on video. Floyd would stop all that. Wouldn't be no more said."
