Camila Cabello Brings Anne-Marie Onstage For Epic Performance of 'Rockabye': Watch

Camila Cabello just wrapped up her Never Be the Same Tour in the U.K., and the pop star went out strong. Attendees of the singer's London show on June 12 were in for a surprise when she brought English singer Anne-Marie for a performance of "Rockabye," the hit collaboration with Clean Bandit.

When Cabello introduced Anne-Marie, the crowd cheered so loudly that they nearly drowned out the music. Once the screams died down, the singers gave a high-energy performance, with fans singing along to every word.

"Rockabye," Clean Bandit’s 2017 single that features Anne-Marie and Sean Paul, made it to the No. 9 spot on the Billboard Hot 100 back in March of last year and spent 27 weeks on the chart.
