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

Motown singing legend Smokey Robinson has been accused of sexual assault by four women who used to work for him, according to a workplace harassment complaint filed Tuesday at a Los Angeles courthouse.

A lawyer for Smokey Robinson said late Wednesday that the sexual assault allegations against the Motown singer were “vile” and “false” and that a lawsuit filed by the four women making the accusations was an attempt to extract millions of dollars from him.
