Rania Hussein Mohammed Tawfik (Arabic: رانيا حسين محمد توفيق ; born October 8, 1981), known as Ruby (Arabic: روبى , sometimes transliterated as Roubi), is an Egyptian singer, actress and occasional model who rose to fame with her debut single "Enta Aref Leih" ("Do You Know Why?") in 2003.
The first music video of her debut single "Enta Aref Leih" (2003), was directed by Sherif Sabri and was a hit on most satellite music stations in the Middle East during the summer of 2003. Ruby was criticized by the media for appearing in the provocative costume of a belly dancer in the song's music video. Despite this criticism, the successful single brought Ruby into the limelight.
