Grammy nominated singer Teena Marie -- once known as Rick James' protégée -- died in her sleep last night at her home in Pasadena at the age of 54 ... TMZ has confirmed with Teena's rep Lynn Jeter.
Relatives found Teena's body Sunday morning at her home.
So far it's unclear what caused the singer's death -- but the Pasadena Police Department tells TMZ they do no suspect foul play. They say it looks like Teena died of natural causes. The L.A. County Coroner's Office will perform an autopsy.
Marie was nominated for a Grammy four times ... her first top ten hit was "I'm Just a Sucker for Your Love."
