Which celebrities were ringside in Las Vegas to watch Floyd Mayweather v Manny Pacquiao?

It seemed as if all of the entertainment business was out in force at the MGM Grand hotel last night.

Floyd Mayweather Jr. vs Manny Pacquiao was the hottest ticket in town and, as you might expect, stars of Hollywood, the music industry and the sports world were their to show their faces.

Power couple Beyonce Knowles and Jay-Z were there, as well as Southpaw's Jake Gyllenhall. Despite his best efforts, a rather inconspicuous-looking Denzel Washington could also be spotted at ringside.

The Raging Bull himself, Robert De Niro, who won the Best Actor Oscar for his portrayal of fighter Jake La Motta in Martin Scorsese's 1980 film, also watched the fight.
