Olivia Rodrigo has become the youngest solo artist to top the UK singles and album charts at the same time.

Rodrigo, 18, from California, secured the feat with her debut album Sour and single Good 4 U.

Sour also recorded the most-ever week-one streams for a debut album – 45.7 million in seven days – overtaking previous record holder Lewis Capaldi.

And Good 4 U is the biggest number one single of the year so far, with 117,000 sales in a week and 13.5 million streams.

Rodrigo had another huge hit in January when she spent nine weeks at number one with her single Drivers License.

She is also the first artist since Sam Smith in 2015 to top the charts with their debut single and album.

In an interview with Billboard earlier this year, she cited Taylor Swift as one of her influences after Swift gave Drivers Licence her seal of approval.

Rodrigo performed a stripped-back version of the song at the Brit Awards earlier this month.

The 18-year-old began as an actress and currently stars in Disney’s High School Musical series.

She plays a character named Nini Salazar-Roberts, who successfully auditions for Gabrielle Montez, a role played by Vanessa Hudgens in the original films.
