Lawyers for four former housekeepers of Smokey Robinson filed a lawsuit against the singer and his wife on Tuesday.

Smokey Robinson and his wife were named in a lawsuit alleging sexual assault, false imprisonment, and labor violations dating back to 2006.

LOS ANGELES (AP) — Smokey Robinson’s lawyer said allegations of rape and sexual assault against him in a lawsuit from four former housekeepers are “vile” and “false.” Attorney Christopher Frost said in a statement Wednesday that the evidence “will show that this is simply an ugly method of trying to extract money from an 85-year-old American icon.”
