R&B singer and songwriter Teena Marie, best known for the hit 1980s singles Lovergirl and Ooo La La La, has died aged 54. The cause of her death is not yet known.
Her friend, percussionist Sheila E, reported on Twitter that Marie had a history of seizures.
Marie, whose real name was Mary Christine Brockert and also used the moniker Lady T, was one of the rare white performers to enjoy cross-over success on America's black music charts.
The ABC reports she signed with Motown Records in 1975 and released her first album four years later. She won four Grammy nominations.
