The BRIT Awards may be hosted by James Corden for the fifth -- and final -- year in a row, but the U.K. music awards ceremony is expanding its audience internationally via live stream for the first time ever.

The actor of Hulu's 'The Wrong Mans' and Disney's upcoming 'Into the Woods' will emcee the British version of the Grammys on Wednesday, which will be presented throughout a concert-style ceremony. Bruno Mars, Katy Perry, Pharrell Williams, Lorde and Disclosure, Ellie Goulding, Bastille and Rudimental are set to perform. And like America's music industry awards night last month, Beyonce is rumored to possibly take the O2 Arena stage.

The Brits will kick off with a performance by the Arctic Monkeys -- a noteworthy headliner that will close a controversial history with the awards show. The band refused to attend the ceremony in 2006 (when they won the breakthrough act award), sent a mocking video message as Wizard of Oz characters in 2007, and gave a sarcastic acceptance speech while dressed as country squires in 2008. Their words were drowned out by awards show organizers, and the band has made piece with the Brits as a an acceptance that they've become one of the U.K.'s preeminent rock bands, following a Glastonbury Festival headline performance last year.
