It was the fight of the century as Floyd Mayweather and Manny Pacquiao battled it out in Las Vegas for a prize of $300 million.

Floyd Mayweather beat Manny Pacquiao to maintain his unbeaten record, in a unanimous verdict win as Pacquiao was out-boxed.

A number of celebrities and sports superstars arrived at the MGM Grand to cheer on both fighters, and millions around the world tuned in their televisions for the Fight of the Century.

Among the A-list stars from the entertainment industry, who watched the event live included Justin Bieber, a close friend of Mayweather, Late-night host Jimmy Kimmel, who was a part of Pacquiao's entourage, Jay-Z and Beyonce, P. Diddy and his model girlfriend Cassie Ventura and others.

Michael J. Fox, Bradley Cooper, Jake Gyllenhall, Ben Affleck, Donald Trump, Paris Hilton, Clint Eastwood and Denzel Washington were also among those present for the fight.

Jamie Foxx sang the US National Anthem before Mayweather and Pacquiao took on each other, and Beyonce caused ample distraction with her show off cleavage in a plunging red dress.

Nicki Minaj also flaunted her curves in a plunging and figure-hugging blue dress, while F1 star Lewis Hamilton kept it low key in a cowboy hat.

Boxers Amir Khan and Mike Tyson, Basketball player Michael Jordan, New England Patriots' Quarterback and supermodel Gisele's husband Tom Brady, and tennis A-list stars Andre Agassi and Steffi Graf were also in the audience.

The fight tuned in thousands of Filipino supporters for Pacquiao, who shot to fame from the streets to one of the world's greatest boxers.

Many thought that the match was predictable as the still unbeaten American Mayweather was much too smart and too quick for Pacquiao.
