Hilary Duff's getting back to her old ways!

The former Disney star was out and about in L.A. today and it looks like all her hard work out is starting to pay off after giving birth to baby Luca. It's as if she was never pregnant!

The 24-year-old actress has been busting her butt caring for her son and keeping up with her workout regime, both of which are daunting tasks, but it's clear that she's taking it all in stride. Guess it won't be long before she turns up the glam!
