Niall Horan performs on stage during KISS 108's Jingle Ball 2016 at TD Garden on Dec. 11, 2016 in Boston.

Niall Horan turned Camila Cabello's dance-ready anthem "Crying in the Club" into a pop-rock jam at his show in Killarney, Ireland, Saturday night (March 10) -- and Cabello has shared a fan-filmed video of his live cover.

"WOWEEEEEE," she wrote in a tweet that also included several handclap and rose emojis.

Horan, in town for his Flicker World Tour, played the song on guitar. While those who weren't at the concert are only privy to part of his performance, it seems he got plenty of help from the crowd, who sang along with him and filled in for Cabello's "Genie in a Bottle"-borrowed vocal hook.
