Floyd Mayweather isn't shaken up by his former friend 50 Cent or his taunts about his reading skills.

In a clip from his episode of All Access, the boxer addressed 50's initial reading challenge and questioned his place in music.

"That's all he challenged me? He gotta raise the stakes," he said. "Does he still make music? I ain't heard him in a while."

After 50's taunts, the boxer posted a few of his checks on Twitter with the caption, "Read this."

Meanwhile, 50 Cent explained to Angie Martinez that comments like the one above were the reason why he targeted him in the first place.

As for his place in hip hop, the rapper dropped a surprise EP with G-Unit titled, The Beauty of Independence last week. His solo album, Animal Ambition was also released earlier this year, selling close to 100,000 units.
