"I have small breasts, obviously," Kate Hudson proudly proclaimed at the 2002 Golden Globes. "It's nice to be able to wear a plunging neckline and have it be elegant."

Looks like Hudson had a change of heart. An insider says in the new issue of Us Weekly that a plastic surgeon performed a small breast augmentation on the actress, 30, in late March. And the mom to son Ryder, 6, looked noticeably fuller on top while poolside in Miami on April 9.

Explains another source, "Kate makes jokes about her boobs, but her chest has always been one of her biggest insecurities."

Hudson's rep did not return requests for comment.
