Today’s celebrity cleavage belongs to a 31-year-old recording artist who got her start in the music business as a contestant on Star Search, and then went on to star in a popular children’s television series.

In 1999, she rose to fame immediately following the release of her debut album, which was a massive commercial success producing three No. 1 singles on the Billboard Hot 100.

While her next two albums garnered her some worldwide success, it was not until she parted ways with her management team and took creative control of her fourth studio album that she entered back into a world full of career triumphs and personal controversy.

Aside from her work in music, she has dedicated much of her time to charitable organizations, human rights and world issues which include her work as a United Nations ambassador for the World Food Program.
