Hilary Duff fans can finally exhale with relief now that she’s performed “Breathe In. Breathe Out.” for the first time ever, more than a decade after its release.

The deep cut from her 2015 album of the same name made it onto the setlist of the singer/actress’ Thursday night (May 14) performance at the El Rey Theatre in Los Angeles for SiriusXM’s Small Stage Series. In a video captured by Billboard, Duff effortlessly belted out the fan-favorite track in a pair of jeans and ethereal pink top with a long train, her voice sounding buoyant and crystal clear.
