Pop singer-songwriter Julia Michaels dropped by "The Late Late Show with James Corden" on Feb. 18. She premiered her duet "What a Time" live with Irish pop star Niall Horan.

"What a Time" is one of the songs on Michaels' newest EP, Inner Monologue Part 1. After opening for Horan's Flicker World Tour in Europe and the U.K. last year, she recorded the song as a duet with the former One Direction member. "Time" closes out the EP. Michaels wrote it with usual collaborator Justin Tranter while Ian Kirkpatrick handled production duties. Dreamy guitar backs her and Horan as they reminisce about better times together. Michaels conjures up warm memories with Horan on this soaring ballad.

On "The Late Late Show with James Corden," Michaels brought to life onstage the park that she sings about in "What a Time." In a star-covered dress, she starts off the performance on a wooden bench. Horan later appears and strolls through the audience looking absolutely dapper. The two meet in the middle and sing the song face-to-face, making the live duet a cinematic moment. What a night, indeed.

"What a Time" featuring Horan is now available on iTunes and Apple Music alongside Michaels' Inner Monologue Part 1 EP. Her first headlining tour in support of the EP will kick off next month.
