UK singer Ariana Grande is 99.9 percent convinced an ex-boyfriend had an affair with another man.

Grande told Metro.co.uk that her new single Break Your Heart Right Back was inspired by the incident.

“There is a song called Break Your Heart Right Back which is about a boy that cheats on a girl with another boy,” she said.

“It's one of my favorites on the album and it's really funny because I believe it has happened to me. I'm not 100 percent positive but I'm 99.9 percent positive.”

The 21-year-old Grande added: “I would rather he cheats on me with a guy than with a girl any day! If I found out my boyfriend was gay, I would be like, 'OK!' I'd be so relieved.”

The song, which features rapper Childish Gambino, the alter ego of actor-writer Daniel Glover (Community), appears on the upcoming album My Everything, which arrives August 25.
