The latest issue of Star Magazine (and this photo from Hollywoodtuna.com ) shows what appears to be a dramatic size increase in Haylie Duff's breasts. They look like they're about to explode out of her shirt. Has she had a recent breast augmentation or did she stuff two grapefruits into her bra?
I would bet on the breast augmentation . Give her some time and they should settle down nicely, unless she went to Europe and got the 'gummy bear' implants. Then she may be stuck with what she has.
