Welcome back, Hilary.
Following last year's underwhelming return, "Sparks" is the glorious pop gem we've been waiting to hear from Miss Duff.
She whistles her way back onto our
Tidal Spotify playlists with the dreamy synth-pop song, which was co-produced by Bloodshy and co-written by Sweden's It Girl, Tove Lo.
Hilary sounds confident and mature as she sings about a new love affair, "Turn the lights down low and kiss me and dark / 'Cause when you're touching me, baby I see sparks."
Listen to the summer smash below.
