Gwen Stefani is not holding back in her new single "Somebody Else's," which arrived on Friday (Sept. 20).

The pop singer sings of a past relationship that was so toxic that she isn't even upset that her ex has moved on with someone else.

It's a song many scorned lovers can appreciate, but it's hard not to wonder if she's drawing from real life experiences. Stefani wrote the song alongside Dark Waves.

"You're somebody else's / And it doesn't even break my heart / You're somebody else's / And I pray for them, whoever they are / Everyday with you is rock bottom / Leavin' you saved me, my God / Look at me blossom / You're somebody else's problem," she sings in the chorus.

Oh, just wait. It gets better:

"Narcissistic, semi-psychotic / So manipulated, I bought it / Every time, but not this time / You gaslit my world, it was burning / Had to leave before it stopped turning / So happy I could cry / 'Cause you're not mine," Stefani pines in the bridge.

"Somebody Else's" is the first offering from Stefani's new album, Bouquet. She first teased her fifth studio album on Sept. 18. Included with the announcement was a photo of herself wearing a cowboy hat, which led to speculation that her next project could be country-leaning.

While this first single certainly draws inspiration from her pop background, there is something about the opening guitar lines that feels country. Only time will tell if that continues in the other tracks.
