A day before Hilary Duff's highly anticipated new single 'Chasing the Sun' is set to premiere, a clip of the summery track has leaked online.

Duff -- who rocks a personality as upbeat and bubbly as her song -- has been super pumped about 'Chasing the Sun,' teasing fans with snippets of the tune and even banner planes. And now fans can listen to the track just a little early!

Fans of the former 'Lizzie McGuire' star's previous albums will love the new single -- her first in six years and reportedly co-written with Ed Sheeran -- which is filled with the same beachy, pop vibes as songs like 'Why Not' and 'Come Clean'. We love the retro feel of the tune, which totally takes us back to the late '90s/early 2000s with its bubblegum sound.

"Won't miss out on the fun / Gotta get it while our hearts are young," Duff sings on the catchy chorus. "I'm chasing the sun." Listen to a preview above!
