Pregnancy is zapping actress Jessica Alba of her famous energy.
The Fantastic Four star admits she used to be just like "the energizer bunny" but now she has to take care to eat regularly or risk becoming a tired monster.
She says, "I have to make sure that I'm eating more of the right nutrients and vitamins, but I'm not used to eating this much.
"I've had to take time out of the day to eat before I get cranky and rundown and tired. Before I was just like the energizer bunny."
Alba and her fiance Cash Warren are expecting their first child together this summer (08).
