R&B singer R. Kelly, long trailed by lurid rumors, has been charged with aggravated sexual abuse involving multiple victims dating back two decades. A timeline of his life and career:

— Jan. 8, 1967: Robert Sylvester Kelly is born in Chicago to Joann Kelly, a school teacher. R. Kelly is third of four children and lives with his family in Chicago's housing projects. Little is known about his father.

— 1975: At age 8, Kelly begins singing in church. Around the same time, his mother teaches him how Stevie Wonder sings by putting a nickel on the record player needle to slow down the revolutions. "So the runs could go really slow and then you learn them," Kelly told ABC News in 2004.

— 1979: At age 12, Kelly said, he "experienced a lot of things at a very young age that I don't know if I was supposed to," including witnessing older youth rape one of his girlfriends.

— 1983: At age 16, his mother moves the family from the projects and enrolls her son at the prestigious Kenwood Academy, a Chicago public school. Kelly meets his mentor, Lena McLin, who chairs Kenwood's music faculty. "She was my second mother. She made me feel I could do anything," Kelly told People in 1994.

— 1984: At age 17, his music teacher places him in a local talent show to perform a version of "Ribbon in the Sky," a Stevie Wonder song. "That night it was like Spider-Man being bit. I discovered the power you get from being onstage," he told Newsweek in 1995. In the years that follow, he performs in Chicago's subway stations full time with his Casio keyboard, often pretending he's blind to avoid arrest.

— 1990: R. Kelly's R&B group MGM wins the $100,000 grand prize on the syndicated television talent show, "Big Break," hosted by Natalie Cole. Because of money disagreements, that was the last time the group performed. Music executive Wayne Williams of Jive Records discovers Kelly singing at a barbecue that summer.
