"Halle Berry might not be the youngest mum-to-be of the group, but she still managed to steal the top spot from Kate Middleton and Frankie Sandford," said Mark Pearson, Chairman of MyVoucherCodes.co.uk.
"Many celebrities look great during pregnancy, but it has to be remembered that they might look entirely different without stylists and personal make-up artists. Each of the mums-to-be in our top ten look healthy and like they’re really enjoying their pregnancies, something that I think is a big contributing factor to that pregnancy ‘glow’ we hear so much about."
