Ariana Grande: 'I'm 99.9% Sure My Ex Cheated with a Guy'

Ariana Grande is getting personal!

While discussing her song "Break your Heart Right Back" -- which samples Diana Ross' classic "I'm Coming Out" -- off her new album My Everything, Ariana reveals to Attitude magazine that she's almost certain her ex-boyfriend cheated on her with another guy.

"It's about a boy who cheats on a girl with another boy. That's a very fun concept," she tells Attitude in a new interview. "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."

Though according to Ariana, 21, the unusual situation is actually more ideal.

"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," she adds.

Ariana's love life has been making headlines recently, with reports that she's now dating rapper Big Sean, 26, after breaking up with her ex Jai Brooks of the YouTube group The Janoskians.

She also recently took the time to reportedly defend her brother Frankie Grande after a fan left a homophobic comment on her Instagram, calling him a "homo."
