Kate Moss on a recent shoot for YSL

She has been criticised for looking worryingly thin but Kate Moss may yet become a more suitable role model.

The 34-year-old is embarking on a healthy-eating regime apparently in the hope that it will boost her fertility.

"Kate is taking her diet and health seriously," says an insider.

"She has been taking extra iron supplements and stocking up on spinach and greens."

The party-loving supermodel is also said to be planning to give up alcohol and coffee.

Kate has been dating The Kills frontman Jamie Hince following her split from Babyshambles rocker Pete Doherty last June and I'm told the couple have already discussed a baby.

"Kate is desperate to have another child," my source adds.

"She loosely follows the same diet as Gwyneth Paltrow does, which is Dr Nish Joshi's cleansing diet, but she has tailored it around trying to get pregnant."
