There is an article about Cassie at USATODAY.com:

A gift keeps giving: Cassie had just started working with producer Ryan Leslie when her mother asked her to record her a song for her birthday. Cassie and Leslie did a sexy duet called Kiss Me, and when Leslie played it for music executive Tommy Mottola, he offered to be her manager. She later signed a record deal with Diddy's Bad Boy Entertainment. Cassie, who moved to New York last year after graduating high school, says Leslie wrote most and produced all of her album with little interference from heavy-hitters Mottola and Diddy. "They saw the chemistry we had. People know that I'm not a super singer like Aretha Franklin or anything like that, but you realize the love of music between me and Ryan is great. So we want to just have fun and make music that people can sing and dance to."
