Music fans will be happy to hear that Channel O will be broadcasting the 2012 Billboard Music Awards live on Monday 21 May at 02:00 and a repeat on Vuzu at 20:30. Today it was announced that Chris Brown has been added to the list of superstars set to perform at the 2012 Billboard Music Awards in Las Vegas. The R&B star is also a finalist in four Billboard Music Awards categories, including Top Male Artist. Hosted by Julie Bowen and Ty Burrell - who play the uptight mom and goofball dad on the hit comedy Modern Family - the duo will have plenty of star power to wrangle during the much-anticipated broadcast, with Usher, Justin Bieber, CeeLo Green, LMFAO, Nelly Furtado, Kelly Clarkson, Linkin’ Park, Carrie Underwood, LMFAO and The Wanted already announced as performers. Adele, LMFAO, Rihanna, Lady Gaga and Lil Wayne lead the finalists for the 2012 Billboard Music Awards. Adele takes the lead as a finalist in 18 award categories, while LMFAO is a finalist in 17 categories. Rihanna lands in 13 categories this year, after leading the pack with 18 category appearances in 2011. Lady Gaga and Lil Wayne each snagged a spot in 10 categories. The awards will reflect Billboard's chart rankings based on key fan interactions with music, including album sales and downloads, track downloads, radio airplay and touring as well as streaming and social interactions on Facebook, Twitter, Vevo, Youtube, Spotify and other popular online destinations for music. These measurements are tracked year-round by Billboard and its data partners, including Nielsen Entertainment and Next Big Sound. The awards will be based on the reporting period 1 March 2011 through to 29 February 2012. Top artists will be recognised in a variety of genres, including R&B, Rap, Pop, Country, Rock, Latin and Alternative. The awards show will take place at the MGM Grand Garden Arena in Las Vegas, Nevada.
