Beyonce 'Single Ladies' (Sessions)

A few years ago, while well on the road to superstardom, Beyonce Knowles revealed that she channels her inner diva, Sasha, when performing with Destiny's Child. Now, after two platinum solo albums and an impressive film career, the singer has fully embraced her alter ego and even given her a last name befitting of a sexy, firecracker performer. On Beyonce's new album, 'I Am ... Sasha Fierce,' Sasha has her own voice and personality, which greatly differs from the singer's quiet and classy disposition. "It's definitely exciting to have an excuse to be so over the top," she admits.

Inspired by Barbra Streisand, the Carpenters and Prince, 'I Am ... Sasha Fierce' tells two stories. The first story emanates from the singer's love of ballads. "I love songs that are emotional and make you think -- make you feel some type of emotion," Beyonce says. The second half, Sasha's half, tells a tale of an audacious woman who flaunts her very high self-esteem on the album's possible next single 'Ego,' and taunts commitment-phobes on 'Single Ladies.' Luckily for us, the singer brought both sides when she took over our New York studio, and ran through her hit single 'If I Were a Boy,' along with 'Single Ladies,' Etta James' 'At Last,' 'Me, Myself and I,' and 'Irreplaceable.'
