Hilary has been working hard, trying to lose her post-baby weight and get her body back in shape. She must have had quite a workout recently. She tweeted, “Holy sore body!!! @soulcycle kicked my booty!!!! Ouchieee.”

That same night Hil tweeted, “No better feeling that a peaceful baby sleeping on your chest…wonder what he’s dreaming about? #happymommy”
