Let's take a moment...to check out Hilary Duff's tush - what a fit butt!  Now for those who are saying "why is she checking out her butt," you know as woman we look at everything on a girl's body, and I have to compliment Hil on her ass-sets!  It's no different than saying she has nice abs, legs, arms, etc.

Again, Hilary is leaving a pilates class at V Pilates Tuesday (July 14).  Keep up with the good work Hil!  For more photos, continue here.
