More people are getting butt augmentation surgery than ever before.

According to the latest statistics provided by the American Society of Aesthetic Plastic Surgeons, over 21,000 people underwent the procedure in 2014, marking an 86 percent increase from the previous year. And the “booty boom” trend seems to be continuing into 2015.

“I’ve seen a 20 percent increase over this past year,” plastic surgeon Dr. Matthew Schulman, who performs the most buttock enhancing procedures of any doctor in the Northeast, tells PEOPLE exclusively.

This year, Schulman performed over 300 butt augmentations, and credits Kim Kardashian with making the elective surgery so popular.

“Kim Kardashian was huge for the ‘booty boom,’ ” he says. “She put her butt out there for everyone to see and embraced it. I think stigma about curves has gone away [because of] people like Kim Kardashian, Nicki Minaj and Sofia Vergara.”

While the middle Kardashian still reigns as the queen of most requested butt, her younger sister Khloé is not far behind, along with Minaj, Vergara, Jennifer Lopez and – for those who desire a more athletic shape – Jessica Biel.

Another big cause of the “booty boom” has been the increase in popularity of social media and the rise of Instagram stars like Jen Selter, says Schulman, who says Selter’s butt is also a popular request.

The two most popular butt enhancing procedures are buttock implants and Brazilian Butt Lifts, both which cost upwards of $8,500.

Schulman recommends staying away from butt injections, which are not FDA approved, and are illegal within the United States.

“It can cause an inflammatory reaction or infection,” he warns. “Or it can be inadvertently injected into a blood vessel and cause death.”

If you are considering going under the knife to boost your derriere, Schulman emphasizes the importance of going to a board-certified plastic surgeon working in an approved medical setting.
