Delta Lea Goodrem (born 9 November 1984) is a multi ARIA Award winning Australian singer-songwriter, pianist and Logie Award winning 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 musical output usually falls under the pop and ballad genres 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) and dance-pop.

To date, Goodrem has achieved eight number one ARIA singles and multiple UK Top 10 singles. Her debut album, 2003's Innocent Eyes, made her one of Australia's highest selling female recording artists, spending 29 weeks at #1, selling over a million copies in Australia and another 1.5 million internationally, debuting at #2 in the UK.

In 2003, at the age of 18, amidst her blooming career, Goodrem was diagnosed with Hodgkin's Lymphoma, a form of cancer which affects the immune system. She has since made a full recovery and now spends much of her time promoting cancer charities.

In 2004 Goodrem released Mistaken Identity, her second studio album which entered the ARIA charts at #1 and gained multi-platinum status. In 2005, Goodrem embarked on The Visualise Tour, her debut concert tour of Australia, combining songs from both Innocent Eyes and Mistaken Identity.

Goodrem released her third studio album, self-titled Delta, on October 20, 2007 to yet another number-one debut, gaining multi-platinum status within the first few months of release. Goodrem also shifted attention to different markets, releasing the album in the Far East and the USA. In January 2009, Goodrem will embark on the Believe Again Tour of Australia to support her third studio album. To date, she has sold 3.5 million albums worldwide.
