Rejoice! Hilary Duff, aka the girl who brought us catchy classic songs "Come Clean" and "Why Not," has a brand new song and it's as infectious as we could've hoped!

Featuring a smooth whistling hook over a synthesized dancefloor beat, "Sparks" sees Duff fully embracing her new sexy persona with lyrics, "Turn down the lights down low and kiss me under the dark / 'Cause when you're touching me baby I see sparks / You make my heart go." We think it's the perfect song to blast while you're getting ready for a girls' night out. Listen to it above.

If everything we've seen recently from the star is any indication, 2015 is basically going to be the year of the Duff. Not only does she star in the brand-new show, Younger, the former Disney teen queen is celebrating her newly single lifestyle. She opened up about her divorce from Mike Comrie in her cover interview for Cosmopolitan, showed off her toned abs in a slinky bikini photo on Instagram, and debuted defiantly hot teal hair at SXSW.

What do you think of Hilary's new song? Are you on board for a full Duff comeback this year?
