Divas return: Christina Aguilera and Alicia Keys
"The Voice" judge Aguilera helped amp up Maroon 5's No. 1 hit single "Moves Like Jagger" in 2011, but in 2012, she's looking to make new strides on her own. HOT 95-7 claims the singer will be releasing a new single "Love Your Body" in January, with a full announcement on a 2012 album imminent. Idolator says that clips of it's R-rated version -- "F*ck Ur Body" -- is making its way around the YouTubes. Could the track make up for the mixed reviews and bad sales of 2010's "Bionic?"
Meanwhile, Alicia Keys spent 2011 raising her newborn son and celebrating the 10-year mark of "Songs in A Minor." She also made her bow as a Broadway producer for "Stick Fly." But she also introduced a new song "A Place of My Own" during her iHeart Music Festival spot, and told "Good Morning America" in December she was working on finalizing a complete new album, her first since 2009's "The Element of Freedom."
