In 2020, "Chromatica" became the sixth US No. 1 album for which American singer?

Stefani Joanne Angelina Germanotta (born March 28, 1986), known professionally as Lady Gaga, is an American singer, songwriter, and actress. She is known for her image reinventions and musical versatility. Gaga began performing as a teenager, singing at open mic nights, and acting in school plays. She studied at Collaborative Arts Project 21, through New York University's Tisch School of the Arts, before dropping out to pursue a career in music.

"Chromatica" is the sixth studio album by American singer Lady Gaga, released on May 29, 2020, by Interscope Records and subsidiary Streamline. Gaga supervised the production with longtime collaborator BloodPop and a variety of other producers to create a concept album returning to her dance-pop roots, eschewing the stripped-down style of its predecessors "Joanne" (2016) and "A Star Is Born" (2018). "Chromatica" draws inspiration from 1990s house music, seeing Gaga adopt a cyberpunk-inspired persona.

"Chromatica" debuted at the top of the US charts, becoming her sixth consecutive number-one album in the country, and reached the top spot in more than a dozen other territories including Australia, Canada, France, Italy and the UK.
