Because she has!
We love it when celebs actually look like they've been at the gym after being at the gym — it shows us they've put in the hard work!
Check out this pic of Dakota Fanning (above)!
She totally looks BOTH happy and healthy, and it's probably because she feels good after working out!
We'd know that look anywhere!
Love you, Dakota! Hope all is well!
