Amethyst Amelia Kelly (born 7 June 1990), known professionally as Iggy Azalea (), is an Australian rapper, singer, songwriter, model, and music video director. At the age of 16, Azalea moved to the United States to pursue a career in music. Azalea earned public recognition after releasing the viral music videos for her songs "Pussy" and "Two Times" on YouTube. Azalea signed a recording contract with American rapper T.I.'s label Grand Hustle shortly afterwards and released her debut mixtape, Ignorant Art (2011).
Azalea's debut studio album, The New Classic (2014), peaked among the top five of several charts worldwide and received generally mixed reviews. It topped the Billboard Top R&B/Hip-Hop Albums making Azalea the first non-American female rapper to reach the top of the chart. The album was preceded by her debut single "Work", and generated the US Billboard Hot 100 chart-topping single "Fancy". Azalea was featured on Ariana Grande's single "Problem", which peaked at No. 2 while "Fancy" was No. 1. Azalea joined The Beatles as the only acts to rank at numbers one and two simultaneously with their first two Hot 100 entries. She achieved three top-ten hits simultaneously on the Hot 100 with the aforementioned songs along with the album's fifth single, "Black Widow", later that year.
After her debut album, Azalea released a slew of moderately successful singles to build anticipation for her intended second album, Digital Distortion, though a series of label conflicts and personal conflicts saw the project being scrapped. After switching labels again, Azalea released the EP Survive the Summer (2018) under Island Records. Continued disagreements lead to Azalea becoming an independent artist signed to her label, Bad Dreams, through a distribution deal with Empire. Her second album, In My Defense, was released on 19 July 2019.
Since her debut, Azalea has sold 48 million records worldwide, with 22 million singles in the United States alone. Azalea's accolades include two American Music Awards, three Billboard Music Awards, an MTV Video Music Award, a People's Choice Award, four Teen Choice Awards, and four Grammy Award nominations. Azalea's official YouTube channel has accumulated 2.6 billion views, while she has had 13 music videos receive over 100 million views on Vevo.
