Did Nicole Richie get breast implants?

When Nicole Richie showed up to the American Music Awards in a sparkling strapless gown on November 21, she turned a lot of heads. It seemed that Nicole had been gaining weight lately and it all ended up in her chest. But a source for the National Enquirer claims that Nicole's new cup size wasn't a result of healthy eating.

The insider said, "Nicole has worked hard to put on some weight, but she also got breast implants from a Beverly Hills plastic surgeon about six weeks ago. The effect has been amazing. She looks great and feels great. And her new boobs have given her more confidence than she's ever had before."

A plastic surgeon looked at pictures of Nicole and believed that reports of her having had implants were correct. The surgeon told the Enquirer, "Nicole has gained a little weight, five pounds at the most - but her breasts have increased from AA to B, which is out of proportion to her relatively small weight gain."

Still the Enquirer snitch's story doesn't seem to quite add up. While the source claims Nicole had the surgery six weeks ago, Nicole was still looking flat as a board at the Playstation 3 launch on November 8. Perhaps her new stylist just found her a really good push-up bra for the AMAs.
