50 Cent trolls Mayweather after Pacquiao fight announcement

Floyd Mayweather's on-again, off-again friend Curtis "50 Cent" Jackson has weighed in on the announcement that Mayweather is coming out of retirement to fight Manny Pacquaio again.

Jackson, who's been feuding with Mayweather on social media in recent months, poked fun at the boxer on Instagram by saying Mayweather's already gone through all the money he made from the last fight.

Mayweather defeated Pacquiao via unanimous decision in May 2015, and is the early betting favorite for the potential rematch.
