50 Cent isn't letting up on Floyd Mayweather.

The rapper's latest diss to Floyd came on Monday (June 9) when the retired fighter posted a photo of his son after he graduated from high school.

"I'm so proud of my son for doing something that I didn't do, and that's graduate high school. When I was his age I dropped out of school and followed my dream of boxing to take my family out of poverty"- Floyd Mayweather 🇺🇸 Jr(50-0, 27 KO's)

"I'm so proud of my son for doing something that I didn't do, and that’s graduate high school," Floyd captioned the photo. "When I was his age I dropped out of school and followed my dream of boxing to take my family out of poverty."

50 then made fun of the ex-fighters reading skills, as he's done before.

"He can read whatever you need for you,” he wrote.

The most notorious time when 50 brought up Floyd's reading abilities was in 2014 when a lot of people were doing that ice bucket challenge.

The public initially learned of Floyd's questionable reading skills after Charlamagne Tha God leaked audio of him struggling to read a promotional message, which The Breakfast Club host later said he regretted.

Do you think 50 is taking things too far by making fun of Floyd's reading or no?
