NEW YORK (AP) — R. Kelly has long faced allegations of lurid sexual behavior and abuse, some of which have been made public through documentaries or court documents.

The R&B singer is once again heading to court, this time for a federal trial in New York stemming from years of sexual abuse allegations. He denies the allegations against him.

Here is a timeline of Kelly’s life, from his early days in Chicago through his rise and fall as an R&B artist:

— 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.
