Delta Lea Goodrem (born 9 November 1984) is an Australian singer-songwriter, pianist, and actress. Signed to Sony at the age of 15, Goodrem rose to prominence in 2002, starring in the popular Australian soap Neighbours as Nina Tucker, and this assisted her in establishing an international music career. Her repertoir falls under the pop and adult contemporary styles, and heavily features the piano, which she usually plays in her bare feet while performing live. Her music is usually heavily influenced by classical or Adult Contemporary music, and sometimes by others such as alternative pop (pop rock) She is currently the face of Sunsilk, So Good and has recorded a commercial for Wii Sports, Nintendo DS and Proactive. "Predictable" is a pop rock song written by Kara DioGuardi, Delta Goodrem and Jarrad Rogers, recorded by Goodrem for her first album Innocent Eyes (2003). Released in the last quarter of 2003, the single peaked at number-one on the Australian ARIA Charts, becoming Goodrem's fifth number-one single in Australia. This achievement in itself broke the record set by Goodrem herself for the most amount of consecutive number-one's from a debut.
