Milla Jovovich has gone "cold turkey" on peanut butter because she was gaining so much weight.
The former model - who is expecting her first daughter with fiance, director Paul W.S. Anderson in November - has gained almost 70 pounds in the last four months after gorging on the nutty spread.
She said: "I'm happy to tell all the pregnant ladies out there that I've gone from 130 pounds to 193 pounds. It's a lot of weight to put on quickly and I only have myself to blame.
"I could eat peanut butter sandwiches and bagels all day. I see no problem with it.
"Of course my doctor does see a problem with it. So I've gone cold turkey on the bread. I'm doing chicken and veggies and trying to be the healthiest mother.
"But if I could continue with the peanut butter, I'd be the happiest mom in the world!"
The Resident Evil: Extinction actress also revealed her feet have swollen so much she can no longer fit into her old shoes.
She told the Chicago Sun Times: "Honey, my bones seem soft now and my feet are killing me. I can barely wear flip-flops. And now I have a whole new appreciation for my old body.
"Now, my feet have grown three sizes. They don't tell you that part, either. Right now I can't get out of my stretch empire T-shirt dresses."
