Mary Christine Brockert (March 5, 1956 – December 26, 2010), better known by her stage name Teena Marie, was an American singer, songwriter, and producer. She was known by her childhood nickname Tina before taking the stage name Teena Marie; she later acquired the nickname of Lady Tee (sometimes spelled Lady T), given to her by collaborator and friend, Rick James. 

She was known for her distinctive soulful vocals, which initially caused many listeners to believe she was black. Her success in R&B and soul and loyalty to these genres would earn her the title Ivory Queen of Soul. She played rhythm guitar, keybords and congas. She also wrote, produced, sang, and arranged virtually all of her songs since her 1980 release,Irons in the Fire, which she later said was her favorite album.
During the 1990s, Teena Marie's classic R&B, soul, and funk records were either smpled by hip-hop artists or covered by R&B divas. Teena Marie herself is regarded as something of a pioneer in helping to bring hip-hop to the mainstream by becoming one of the first artists of her time to rap one of her singles—the aforementioned "Square Biz". In the hip-hop portion of that song, she mentions some of her inspirations: Sarah Vaughn, Johann Sebastian Bach, Maya Angelou, Shakespeare an Nikki Giovanni. In 1996, the Fuges paid tribute to her by interpolating the chorus of her 1988 hit, "Ooo, La, La, La", into its own "Fu-Gee-La".

Tina Marrie is recorded 14 studio albums - most of them were very succeful.
At the time of her death, Teena Marie had been in the process of completing her fourteenth album, Beautiful. It was finished posthumously by her daughter, Alia Rose. Beautiful was released on January 15, 2013.
