Queen Latifah is a Grammy-winning American rapper/singer and Academy Award-nominated actress.
Latifah started her career beatboxing for the rap group ?Ladies Fresh?. In 1988, local DJ Mark the 45 King heard a demo version of Latifah’s single, “Princess of the Posse”, and gave the demo to Fab Five Freddy (who at the time hosted Yo! MTV Raps). Freddy helped Latifah sign with Tommy Boy Records, which released her first album, ?All Hail the Queen?, in 1989.
From 1993 to 1998, Latifah had a starring role on ?Living Single?, a FOX sitcom; she also wrote and performed its theme music. She began her film career in a supporting role in the 1991 films ?House Party 2?, ?Juice?, and ?Jungle Fever?,.
Latifah first attracted notice for her role as a lesbian in the 1996 box-office hit, ?Set It Off?, and subsequently had a supporting role in the Holly Hunter film Living Out Loud (1998) and played the role of Thelma in the 1999 movie adaptation of Jeffrey Deavers’ ?The Bone Collector? alongside Denzel Washington and Angelina Jolie. Although she had already received some critical acclaim, she gained mainstream success after being cast as Matron “Mama” Morton in the Oscar-winning musical ?Chicago?, the recipient of the Best Picture Oscar. Latifah received an Academy Award nomination for “Best Supporting Actress” for her role.
