50 Cent is to be paid $500,000 for performing in Las Vegas over the weekend of the Floyd 'Money' Mayweather versus Manny Pacquiao fight.

According to TMZ.com, the rapper is going to earn the huge sum to take to the stage at nightclub Drai's on Friday night (01.05.15) the day before the big world championship boxing bout on Saturday evening (02.05.15).

The gig is not 50 Cent's only impending big pay day. The hip hop star has also reportedly negotiated a deal with Effen Vodka to bank $500,000 for a performance at a Pool After Dark part in Atlantic City later in May.

Perhaps the rap superstar is trying to cover his massive wager on Mayweather in case the undefeated pugilist records his first loss against 'Pacman' Pacquiao.

50 Cent has bet $1.6 million on a Mayweather victory in the bout, which is being dubbed the biggest fight of the 21st century.

The odds on a Mayweather currently make him a 8/15 favourite.

But the 'In da Club' hitmaker is confident of seeing a return on his massive wager, recently saying: "Champ (is) gonna smoke him. It's gonna look like it was pumped up for no reason."
