Where Have They Been? Pop Stars Missing In Action
5. Britney Spears
Where Have They Been?: 2011 saw the release of Britney's seventh album 'Femme Fatale' as well as a mammoth tour, but 2012 has mostly seen her enjoying her recent engagement to Jason Trawick, as well as signing up for one of TV's hottest reality shows. When Will They Be Back?: While a new album from the pop princess seems a long way off yet, Britney is already back on our screens serving on the judging panel for The X Factor USA, and is set to feature on a collaboration with Will.i.am on his new album '#willpower'.
