LOS ANGELES - Jessica Alba battles demons in her new horror movie The Eye, but the six-month-pregnant Hollywood actress says she turns into "Satan" if she does not satisfy her own food cravings.

Alba does not have one simple craving.

The 26-year-old craves food.

Any type of food.

"Every couple of hours I turn into Satan if I don't eat something," Alba laughed during an interview in Los Angeles.

Wearing a red empire-waisted Gucci dress that exposes a slight baby bump, Alba believes "the gods answered my prayers" when she became pregnant to fiance Cash Warren last year.

The couple met while making the original Fantastic Four film four years ago.

"I was in shock at first," Alba said when she first saw the positive pregnancy test.

"But we're so happy.

"My family, everyone, are just thrilled.

"It all seems to be perfect timing.

"Everything fell into place the way it was meant to."

A paparazzi favourite, particularly because of her expanding waistline, Alba is chased around Los Angeles every time she leaves her Hollywood Hills home.

Despite growing up in front of the public eye - she made her first movie when she was 14 - Alba is baffled by the attention she receives from photographers who trail her car to the supermarket or on other expeditions.

"When I started acting it wasn't this bad," Alba said.

"It's bizarre and it seems like anybody can go buy a camera and call themselves a paparazzi and stalk people for a living.

"It's really strange.

"I'm not doing anything interesting or salacious.

"I'm not trying to be out there.

"I'm just going to the gym or getting my groceries, normal stuff."

The thought of leaving Los Angeles has not crossed her mind because her family and most of her friends live in the city.
