New York rapper 50 Cent has found an unlikely foe in Floyd Mayweather Jr.‘s ex-girlfriend. The G-Unit boss and vixen Doralie “Bad” Medina have suddenly clashed with one another.

Last night, Fif and Medina randomly took shots at one another in a series of Instagram posts.

This week, Medina reacted to Floyd possibly expecting a baby with his girlfriend Jennifer Duran.

Back in late June, 50 Cent clowned Floyd for allegedly spending nearly $20 million on a diamond watch.

According to reports, Mayweather dropped a solid $18 million on his Jacob and Co. watch.

The jaw-dropping watch, designed by Jacob and Co., cost the former boxing champ $18 million—no, not billion—and is made of 18-carat white gold, 260 carats of emerald-cut diamonds and individual stones up to three carats. “This my new timepiece, it’s called ‘The Billionaire Watch,” Mayweather informed his Instagram followers. “If you don’t know about it, google Billionaire Watch. That’s $18 million on the price tag.” (Page Six)
