Is it just us, or does Hilary Duff appear to love her Pilates class just as much as she loves her baby Luca?!? LOLz
Either her class was exhilarating, or she was just feeling her new iPhone case with her cherub's name written across it.
Whatever was going on, we're just happy to see that Hilary is getting her fitness on. She's gonna be back to her pre-baby weight in no time!!
