hilary-duff-01Stepping out for her daily workout, Hilary Duff was spotted attending a Piloxing class in Los Angeles yesterday (July 29).

The “So Yesterday” songstress looked a bit tuckered out as she returned to her car after the session to find shutterbugs waiting for her.

In related news, there are rumors running rampant that Hilary is so bent on looking perfect for her wedding that she’s turning to plastic surgery.

A tabloid source claims, “Hilary is obsessed with looking her best on her wedding day. She recently got her boobs done and has been getting Botox and fillers to make her face look as good as possible. She is determined to work out six days a week, and she brings Mike along so they can motivate each other. She’s lost 10 pounds already!”
