Penelope Cruz is immune to jetlag. The Spanish-born star spends so much of her life traveling across the world her body never knows what time of day it is.
She is quoted as saying: "I think you reach a point where you have so much jet lag that you can't feel the jet lag anymore. It's just like regular. I wake up and I really don't know which city I am in. I just get off the plane find some make-up and shower and here I am. It's a big adventure."
