Sultry British singer Adele, whose second album “21” is the world’s top-selling record this year, earned seven nominations — all of them for her hit single “Rolling in the Deep.” Rapper Kanye West was the top male nominee, with seven nods for his futuristic “E.T” collaboration with Perry as well as his own music videos for “All of the Lights” and “Power.” Soulful “Grenade” singer Bruno Mars earned four nominations while Beyonce, Eminem, rock band Thirty Seconds to Mars and female rapper Nicki Minaj racked up three nods apiece. The awards will be handed out during a televised live show in Los Angeles on Aug. 28. Winners are picked by public voting. The nine nods for Perry, 26, were the climax of an extraordinary 12 months that has seen the once struggling gospel singer reinvent herself as a pop sex kitten with a string of hits like “California Gurls,” “Teenage Dream” and “Firework.”
