10 Best Celebrity Appearances in WWE

#4 Floyd Mayweather

Floyd Mayweather smashes Big Show with a steel chair.

Floyd Mayweather is one of the most accomplished boxers in the history of the sport. His technique and speed have made him a very wealthy man, and his fame has spread beyond the world of professional pugilism.

Fans were intrigued when the rumors started circulating that Mayweather might be making an in-ring appearance at WrestleMania.

But when his opponent wound up being the Big Show, a man who dwarfed him by three hundred pounds, the level of excitement went through the roof.

The match was hyped up by Show kneeling down and begging Mayweather to give him his best shot. Mayweather obliged, breaking the Show's nose and setting the stage for a no-holds barred confrontation at Wrestlemania.

Mayweather won the hardcore match, making him undefeated both in the WWE and at Wrestlemania, an egregious accolade indeed, though much happened to the show's chagrin.

Big Show has been WWE's lab rat for facing celebrities from different walks of life. Akebono, Floyd and Shaq are just some of the popular names.
