Tina Barrett was born in Hammersmith, London, England to an English father and a Guyanese mother.

They also had a series of TV shows, which were: Miami 7, L.A. 7, Hollywood 7 and Viva S Club, and they also starred in a film, Seeing Double.
When the group announced they were to break up, Barrett expressed interest in working on a solo career, but she was unsuccessful to sign with a label or an entrepreneur.
Barrett is also heard in a song called "Boom" by Old Boy which also features rapper Nasty Jack; an accompanying music video has been shot but has not yet been released.
