7. Hilary Swank
Another Hollywood favorite around whom the breast implant debate rages harder than an uncontrollable trouser tent, Hilary Swank certainly seems to have come on in a big way from the seemingly more flat-chested days of her early career. Do we think she's had breast augmentation? The jury's still out, but put it this way: after her Oscar-winning performance in 1999â€²s Boys Don't Cry, it seemed as though it wasn't just her ego that suddenly got significantly inflated. Whether her rack was just better on display in an awards-ceremony dress than in the clothes that Hollywood's costume departments made her wear, or whether she had surgical help is, as we say, still up in the air. But if they are natural, one thing's for sure: either she was hiding those million dollar babies or they've somehow grown a great deal in value.
