Ariana Grande reunites with ex-boyfriend Nathan Sykes on a new version of his single “Over and Over Again.” The pop diva and former Wanted member serenade each another on the romantic piano ballad.

“When I’m with you I lose track of time / When I’m without you, you’re stuck on my mind / Be all you need till the day that I die,” they sing.

They previously collaborated on “Almost Is Never Enough,” which appeared on Ariana’s 2013 debut Yours Truly.

The “Focus” singer is currently putting the finishing touches on her third album. During her appearance on “Jimmy Kimmel Live” last night, she revealed that she’s had a change of heart about the album title, Moonlight. “A really long time ago, I was convinced that it was gonna be called Moonlight because it’s one of my favorite songs that we did for the album,” she said. “Now there’s this other song that has sort of thrown me for a whirlwind and I love it so much.”
