Proving that interest in Miranda Kerr is sky high, a rumor about her having plastic surgery spread like wildfire on Tuesday (March 18).

According to a doctor who has not treated the Aussie model, "Miranda appears to have undergone a very tasteful breast augmentation. 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."

However, a friend of the 30-year-old beauty says it's all hogwash, telling E! News, "It is completely untrue."

Declining to address the ridiculous claim, Miranda instead posted an adorable photo of her sleepy terrier on Instagram with the caption, "Someone doesn't want to wake up this morning."
