Ros

Ros is a character in Game of Thrones.

Ros Serey Sothea was a Cambodian singer. She was active during the final years of the Sangkum Reastr Niyum period and into the Khmer Republic period. She sang in a variety of genres; romantic ballads emerged as her most popular works. Despite a rather short career she is credited with singing hundreds of songs. She also ventured into acting, starring in a few films. Details of her life are relatively scarce. She died during Democratic Kampuchea's regime of the Khmer Rouge but circumstances of her fate remain a mystery. King Norodom Sihanouk granted Sothea the honorary title "Queen with the Golden Voice".

Sigur Ros is an Icelandic band.

The name of the principal in School of Rock is Ros, but I assume it's a nickname.

Ros is Frasier's producer on the show "Frasier."
