Olivia Rodrigo's concert was filled with excitement when she brought special guest Lily Allen on stage for a surprise duet during her Guts World Tour stop at London.
During her performance at O2 Arena on Friday, May 17, Olivia called Allen to stage and introduced her to the crowd.
The Grammy winner gushed, "The best day of my whole career was when I got to sing with her a few years ago at Glastonbury. I absolutely adore her. Please give a warm welcome to the incredible Ms. Lily Allen!"
The duo sang Allen's hit song Smile together, taking turns singing the lead vocals. After the performance, they shared a warm hug, and Olivia asked the crowd to applaud again for Allen.
Shortly after the concert, Allen took to her Instagram account to share some backstage picture along with heart felt note.
She penned, "Been a while since I’ve sang at the O2. what a lovely crowd, what a lovely crew. Thank you @oliviarodrigo x"
The Déjà vu songster also posted a video of their performance on her Instagram story, noting, "Last night at the O2 with the coolest girl in the whole world."
She also shared a cute photo of the two of them together backstage.
This reunion marks nearly after two years since their last performance together at Glastonbury in 2022.
