Authorities say they investigated a sexual assault allegation against Smokey Robinson in 2015, but no charges were filed because of insufficient evidence.

Frances and Smokey Robinson's lawyers want a lawsuit from four accusers to be tossed out and claimed the couple treated them with "utmost kindness."

Smokey Robinson, who is under criminal investigation after four former housekeepers accused him of sexual assault, filed a $500 million defamation lawsuit against his accusers, alleging the women orchestrated with their attorney to make a “public spectacle” to extort money.
