Olivia Rodrigo and Lily Allen Reunite for 'Smile' Duet in London

The surprise performance at the O2 Arena marks their first collaboration since Glastonbury 2022.

Rodrigo introduced Allen as the 'most clever songwriter' and 'coolest girl in London.'
The duo performed Allen's 2006 hit 'Smile' to an enthusiastic crowd.
Rodrigo's debut album 'Sour' became the most-streamed album by a female artist on Spotify.
Allen last joined Rodrigo onstage to protest the overturning of Roe v. Wade in 2022.
Rodrigo's Guts World Tour continues with dates across the U.S., Asia, and Australia.
