“Pretty Boy” Floyd Mayweather Jr. opted for a lucrative investment of his skill in the time before the September rematch against Oscar De La Hoya, and decided to appear on Wrestlemania 24 on March 30, for a “mere” salary.

The event is set to take place at Citrus Bowl in Orlando, Florida, and according to the World Wrestling Entertaiment Chairman Vince McMahon, Mayweather will win $20 million for his appearance at the annual event.

“I had approached (WWE) about a year ago, but it didn’t fit into our schedule,” Leonard Ellerbee, Mayweather’s advisor, said in a press conference at Staples Center, confirming the boxer’s paycheck.

“It’s entertainment. You have a chance to just be you and do what you want to do,” Mayweather also explained at the press conference on Monday, the Associated Press reports. “I run Vegas and I run L.A. and I will run the WWE,” he added.

Mayweather has been in the spotlight and in the entertainment field like no other boxer, gaining both the attention of sports fans and, believe it or not, women of all ages, since his appearance on “Dancing with the Stars.”

It’s a combination of image and rough sport for Mayweather, who says all these “extra-curricular” activities will not interfere with his career as a boxer.

WWE star Rey Mysterio will prepare him for the round against Big Show: “I weight three times as much as he does,” Big Show bragged. It’s not fair, but I’m a businessman and I see an opportunity for business.”

It seems a bit unfair if we look at the encounter from the weight point of view, as Mayweather, at his 5-foot-8, 150 pounds, stands against 7-feet, 430 pounds, but often big things come in small packages, and Mayweather could give Big Show a big surprise.
