Hilary Duff plays superfan and enjoys a night off from her mom duties at the Post Malone concert in Los Angeles

She's released five studio albums in addition to a host of compilations, live collections and music videos.

But Hilary Duff was simply a superfan on Thursday night as she witnessed Post Malone's magic at The Forum in Los Angeles. 

The 32-year-old actress took a rare night off from her mom duties to belt out a few of his hits with her favorite concert buddy and assistant, Lauren, by her side.

Hilary dressed casually in a cozy cardigan sweater with a row of brown buttons running vertically down her chest. 

She hid her bright blonde hair underneath a black hat and let a few tendrils run loose down her shoulders. 

The mother-of-two added a pair of classic silver hoop earrings to her concert ensemble and showed off her gorgeous complexion with just a touch of highlighter swiped across her cheeks.

While the 24-year-old rapper — who's real name is Austin Richard Post — was certainly the star of the show, concertgoers were beyond impressed when he brought out Ozzy Osbourne to perform the first-ever live rendition of their collaboration, Take What You Want.

The duo will also join Travis Scott on Sunday at the American Music Awards in Los Angeles for the first television performance of the record-breaking song.

Hilary topped music charts more than a decade ago with her sophomore album Metamorphosis, which spawned the hit singles So Yesterday and Come Clean. 

Duff has been hard at work filming the Lizzie McGuire reboot for Disney+ and recently confirmed that co-star Adam Lamberg will return for his role as her best buddy, Gordo.

She also recently signed on to be the Chief Brand Officer as she launched Happy Little Camper and Veeda, plant-based and natural products for moms and kids.
