AceShowbiz - Looking at how they engage in a war of words nowadays, no one would've guessed that 50 Cent and Floyd Mayweather, Jr. were once BFFs. They were on The Money Team, teamed up to launch a film production company in 2011, and the rapper even picked up the retired boxer from jail after his three-month sentence for domestic violence in 2012.

But just a month later, Fif said that Floyd had stopped hanging out with him and he was not cool about it. The actual beef, however, didn't start until the "Power" star started to befriend Manny Pacquiao, who was Floyd's rival. Since then, the former best friends would throw shade at each other on social media, with Fif once dissing the Pretty Boy's intelligence by claiming that the former athlete didn't know how to read. Though there were moments when their feud seemed to cool down, they never patch things up and Fif recently reignited it by poking fun at Floyd's illiteracy again.
