Jessica Alba can't wear heels!

Jessica Alba says motherhood has made her shrink!

The actress who’s pregnant with her second child says rarely gets the chance to wear her favorite high heels.

“Now I have my daughter to run round after I never get to wear heels and I’ve come to love flats,” Alba said.

“Literally, she never stops. She is very active and keeps me fit and out of the gym. So I go for comfort now rather than heels.”

Alba recently admitted she’s frustrated that many people aren’t aware of her true “simple” nature.

“I grew up Catholic so I have lots of guilt I can’t seem to shake away. I’m really just a simple girl from the suburbs,” she said.

“But, a lot of the time, the magazines don’t show that side of me. I’m proud of my heritage.

“I need to find time to be myself and not to be only a personality part of the business.”
