Britney Spears - Britney Jean

Breakup with fiancé Jason Trawick behind her, Britney is back to work. But while the 31-year-old mother of two is now all business, especially on the smash “Work B**ch” and other fitness-club anthems like “Body Ache,” there’s also pain and vulnerability on her eighth studio album. “Perfume” may be her most soul-baring number and the confessional “Don’t Cry” finds her saying goodbye to a lost love. Guests include Britney’s younger sister, Jamie Lynne, on the laid-back “Chillin’ With You, Black Eye Peas frontman will.i.am, the album’s executive producer, on the synthesized thumper “It Should Be Easy” and rapper T.I. on the explosive “Tick Tock Boom.” The album’s otherworldly highlight is “Alien,” a woozy dance number about life in the spotlight. “We all have moments where we feel a little alienated,” explained Britney, about the song’s meaning. Despite that cautionary note, the hard-working pop star’s clearly got her life back on track.
