A host of Hollywood A-listers and sports stars gathered at the MGM Grand to watch Floyd Mayweather comprehensively outpoint Manny Pacquiao in their eagerly-awaited superfight.

Stars received loud cheers from the 16,507-strong crowd when footage of them walking into the arena was televised on the big screen.

Here were a few sightings by the American media.

Million Dollar Baby director Clint Eastwood, perhaps getting some ringside inspiration for a sequel?

(SPOILER ALERT: A sequel might require some fairly bold scriptwriting.)

Paris Hilton looked chuffed to be in the crowd.

Jamie Foxx sung the national anthem – the one from the USA, naturally.

Beyonce and Jay Z looking like actual royalty.

Albeit with a bit more cleavage than you’d expect from Liz…

Raging Bull star Robert De Niro looked like he wanted to show Floyd and Pacman a thing or two.

Drew Barrymore looking very pleased with her hat.

A rather gruff Denzel Washington.

A dapper looking Justin Beiber – he’s bezzies with Floyd didn’t you know?
