In 1998, Khan signed a contract with Prince's NPG Records label and issued Come 2 My House, followed by the single "Don't Talk 2 Strangers", a cover of a 1996 Prince song. She later went on a tour with Prince as a co-headlining act. In 2000, Khan departed NPG and she released her autobiography Chaka! Through The Fire in 2003.[12] The following year she released her first jazz covers album in twenty-two years with 2004's ClassiKhan. She also covered "Little Wing" with Kenny Olson on the album Power of Soul: A Tribute to Jimi Hendrix.

The album featured the hit, "Angel", and the Mary J. Blige duet, "Disrespectful". The latter track went to number one on the U.S. dance singles chart, winning the singers a Grammy Award, while Funk This also won a Grammy for Best R&B Album. The album was also notable for Khan's covers of Dee Dee Warwick's "Foolish Fool" and Prince's "Sign o' the Times". In 2008, Khan participated in the Broadway adaptation of The Color Purple playing Ms. Sofia to Fantasia Barrino's Celie.
