Jessica Alba's "a*s has got bigger by the second" since becoming pregnant. The 'Fantastic Four' actress - who is expecting her first child with fiance Cash Warren - says despite her ever-expanding derriere she is having the "best time ever".

Alba said: "When you're pregnant, your breasts are engorged and your stomach is getting bigger. And the a*s, too, that is getting bigger by the second!"

"But it's awesome. It's the best time ever. I have two movies coming out, a baby, a fiance - everything."

Jessica, 26, is currently taking a break from acting but hopes to get back in front of the camera before the baby is born.

She said: "I don't know if anyone wants me in their movies when I'm six months pregnant. Soon, I'll get the fire and I'll want to work again, but right now it's a time to relax and sit back."

Jessica also revealed she is taking her mind off the downsides of being pregnant by focusing on a domestic project.

She added to People magazine: "I'm more tired and more hungry than normal. But I bought a new house a couple weeks ago so I'm in nesting phase."
