The star has seen similar success in American, where the California native has scored a number one album on the Billboard 200 chart with Sour.

It sold the equivalent of 295,000 album units in the U.S. in the week ending May 27, according to MRC Data, which is the biggest week for an album in 2021.

Taylor Swift had held the title for biggest week for an album this year with her release of Taylor Swift’s Fearless (Taylor’s Version).

Rodrigo’s Sour also had a huge streaming week with it being the second-largest in numbers ever for a non-R&B/hip-hop album, and second-biggest for an album of any genre by a female artist.

Plus, the album scored the largest week, by units, for an artist’s debut charting effort since the Billboard 200 transitioned from an album-sales only ranking to an equivalent album units-based chart on the December 13, 2014 survey, according to Billboard.

Sour was released on May 21 and quickly shot to No. 1 in several countries.

Three singles preceded Sour’s release, all of which reached the top 10 of the Billboard Hot 100.

Initially, Rodrigo saw her star rise as a mainstream artist when the first single, Drivers License, shot to the top of the Hot 100 chart.

It was followed by Deja Vu, which reached number 8, making her the first artist in the chart’s history to debut their first two singles inside the top 10.

The third single, Good 4 U, would also hit No. 1, marking the first time a debut album had ever spawned two No. 1 debuts on the chart.

The album was produced by Dan Nigro and consists of 11 songs, most of which he co-wrote with Rodrigo.

Rodrigo got her big break in the entertainment industry as an actress, which included her roles in the Disney Channel’s Bizaardvark (2016) and Disney+’s High School Musical: The Musical: The Series (2019).
