She's Got Legs!

And she knows how to ice ’em!

Jessica Simpson is on a new fitness mission! She’s rehired longtime trainer Mike Alexander, who got her ass cheeks ready to hang out of those Daisy Dukes! And according to her Twitter, Simpleton is just not what she used to be!

She Tweets:

look at what age can do to a total badass 🙁 At least my legs will look good!

why am i still hurting from our workout earlier? I’m getting old! See you tomorrow with a pouty face and sore buns.

But, for someone who has taken so much undeserved weight-related heat, we’d expect her to be a little more perceptive – though that’s never been her strong suit!

Where were her handlers when she inadvertently labeled herself Hefty?!
