Hilary Duff's Booty-Kickin' Calorie Burn

Posted Friday April 27, 2012 8:01 PM GMT

Continuing to work away at those pesky post-baby lbs., Hilary Duff hit up her local gym in Toluca Lake, California this afternoon (April 27).

Clad in a simply gray top, black yoga pants and a pair of sneakers, the new mom left her week-ending sweat session looking a bit tuckered out.

Prepping for the calorie burning class just a short while before arriving, an excited Hilary tweeted, "Going to see my girl viveca @Piloxing to kick my booty! Hope everyone has a sweeet day."

Despite her perky mood beforehand, the 24-year-old was later left feeling irritated, writing, "Paparazzi are way to aggressive! scary and disturbing!! #Boundaries."
