Chris Rock's swipe at Will Smith and Jada Pinkett Smith for boycotting the Oscars revealed - but will he use it tonight?

Chris Rock posted a tantalizing tweet ahead of Sunday night's Oscars that simply read: 'Get Ready' And while Hollywood holds its breath, material that the comedian tested ahead of his much anticipated monologue has emerged - slamming Will Smith and Jada Pinkett Smith - who have boycotted the show. Indeed, despite the ongoing #OscarsSoWhite row, Rock attacked the couple for their stance at the Comedy Club in LA late on Saturday, making a particularly lewd joke which some in Tinseltown have suggested he won't use because it won't get by the censors.
