Beyonce Knowles has given the organisers of the 2008 Grammy Awards a huge boost after confirming she'll perform at the event whether or not striking writers picket the ceremony. Knowles will join the Foo Fighters, who announced earlier this week (beg14Jan08) they'd cross picket lines to perform at the Grammys on 10 February (08). Event organisers are adamant the show will go on as scheduled, despite the threat of protest from the striking writers. Writers Guild of America (WGA) union members insisted the Los Angeles music ceremony was "unlikely" to receive a waiver, halting potential picket action, earlier this week (beg14Jan08). Justin Timberlake, 50 Cent and Jon Bon Jovi have reportedly pledged their allegiance to the WGA members, who have been on strike since November (07) over new media royalties. The stars have vowed not to cross picket lines. The organisers of the Golden Globe Awards failed to get a waiver from the WGA earlier this month (Jan08), resulting in the cancellation of Sunday's (13Jan08) Golden Globes awards ceremony.
