It looks like Miranda Kerr is the latest celebrity to be accused of plastic surgery as the supermodel's plunging neckline at the Vanity Fair Oscars Party has experts suggesting that she went under the knife.

According to the Daily Mail, the Australian beauty is though to have undergone a breast augmentation to enhance her curves following her split from husband Orlando Bloom last year.

After examining several photos of the brunette, Dr. Anthony Youn, told Radar Online that the KORA Organics founder has had some work done.

The doctor said, "She appears to have gone from an A (cup) to a small C (cup) and her breasts help to create a very nice, curvy figure."

Another expert, Dr Fred Pescatore, author of "The Hampton's Diet" agreed with the comment. He added, "There is no way to go from nothing to something without an operation or weight gain which she hasn't done."

The celebrity news site quips that even though Kerr, 30, has an amazing bikini body, in the past she has noticeably had a flatter chest before she shot to fame.

Following the 2011 birth of her son Flynn, 3, who she shares with Bloom, the supermodel was initially naturally fuller figured and embraced her new curve sporting a series of plunging necklines.

However, towards the end of her marriage to the "Romeo and Juliet" Broadway star Kerr looked a lot thinner and lost her curves.

The model's photos were compared in a before and after perspective. The first photo shows Miranda Kerr at a Victoria's Secret party last year November where she wore a black dress with a plunging neckline.

The dress showed off the model's gorgeous slender frame but her breasts were "undeniably smaller."

While at the Vanity Fair Oscars Party she was curvier in the breast area. While Miranda Kerr's rep has yet to comment on plastic surgery allegations about her, you can make your own assumptions.
