Documents revealing that movie icon Marilyn Monroe had plastic surgery will be auctioned off next month, according to Reuters.

Monroe fans long speculated that the actress, who died at the age of 36, had cosmetic surgery, but the recently surfaced documents, which include X-rays and physicians notes, seem to prove that Monroe went under the knife.

The notes were taken by Dr. Michael Gurdin, who gifted them to the anonymous seller. The seller has turned them over to Julien’s Auctions.

“Nobody really thought about Marilyn Monroe having plastic surgery. It was always speculation – did she or didn’t she?” said Martin Nolan, executive director of Julien’s Auctions. “They thought she was such a natural beauty, they didn’t want to believe.”

Gurdin’s notes explain that Monroe had a chin implant in 1950 and the X-rays include images of the star’s nose and chest.

“Also at that time, going back to the 1950s, people didn’t go for plastic surgery procedures,” Nolan said. “This is very, very new.”

She saw doctors under the alias “Joan Newman,” but early notes by Gurdin also refer to her by her then-married name Marilyn Miller. Monroe was married to Arthur Miller from 1956 to 1961.
