58: Deborah Cox – Powerful Women of 2013

With eight albums under her belt, Deborah Cox is a bonafide songstress who knows how to make music people like. In 1998, she proved that she was a hit maker with the release of 'Nobody's Supposed to Be Here.' The single stayed at the top of the Billboard Hot R&B/Hip-Hop Singles & Tracks chart for 14 weeks -- making it the longest running number-one song on that list ever. It was a record she held for eight years.

In addition to this success, the Canadian R&B singer set her sights on other projects. She has contributed vocals to a number of film soundtracks including 'Hotel Rawanda,' 'Dr. Doolittle 2' and 'Akeelah and the Bee.' She made her Broadway debut in 'Aida' in 2004, playing the lead role.

While she always has her own music in the works, she recently joined the national touring cast of 'Jekyll & Hyde,' playing the role of Lucy. She is also a strong advocate and promoter of HIV/AIDS awareness.
