Crystal Hefner shared her terrifying experience after having plastic surgery.

The former Playboy bunny, who is also known as one of Hugh Hefner's girlfirends and wives, took to social media to reveal that she almost died after going under the knife.

In a lengthy social media post, the blonde beauty shared that she "lost half the blood" in her body from the botched surgery back in October.

"I had a fat transfer surgery October 16 and almost didn't make it through. I lost half the blood in my body and ended up in the hospital needing a blood transfusion. I've been slowly eating my way back to health since then and I am now finally feeling ok," Crystal Hefner's Instagram caption read.

Sporting a flesh colored bandage that covered her breasts, the 34-year-old model also mentioned about learning things the hard way.

"I advocate for being natural since I got very ill and removed my implants and everything else toxic in my body in 2016. I should have learned my lesson the first time but I guess the universe keeps sending you the same lesson until you learn it."

In the end, she sent out a warning to her 3 million followers regarding the unattainable beauty standards that the entertainment industry and social media have set.

Moreover, she pointed out that even at this day and age, "women are overly sexualized."

Hefner also reminded women that everyone is worthy and should not base their value with the culture's absurd beauty standards.

"I feel sorry for the next generation looking up to people whose looks aren't even attainable without lots of filters, makeup, or money and women need to stop feeding into it. "
