Face it, Duchess Kate is not only a princess, but she's also basically a beauty queen -- at least that's what many, many people believe.

The royal has the world's most desirable nose, according to a London-based plastic surgeon, who calls the Duchess' sniffer "mathematically perfect."

Julian De Silva surveyed 1,000 patients to ask them what they thought was the perfect face, which formed a composite of Hollywood elite.

The "world's most desirable face," he said, includes Keira Knightley's eyes, Jennifer Lopez's eyebrows and Penelope Cruz's lips. Women also zeroed in on Angelina Jolie Pitt's cheeks, Reese Witherspoon's skin, Miley Cyrus' forehead, Selena Gomez's chin and Cher's jawline.

Julian noted the Kate's nose was the single most requested thing.

The doctor shared a photo of the face on his Instagram page.

"I created this compiling my patients' plastic surgery requests combining the most requested celebrity features and the result is stunning," he wrote. "The face says a lot about our perception of beauty and reveals the celebrities the public most like to replicate."

He spoke to Daily Mail more in-depth about his findings.

"You will often have a consultation with a patient who will present you with a picture of a well-known person and will say, 'I want to look like that,'" he told the UK-based newspaper. "Thankfully, a lot of the time, it works very naturally to replicate a nose like the Duchess of Cambridge's or eyelids similar to Keira Knightley's. But on other occasions we do have to amend the plans because there are limits to how far you can improve what nature has given you."

Earlier this summer, that same doctor enlisted his team to create software that calculates face shapes to determine the perfect face from an analytical standpoint, which was called the Greek Golden Ratio of Beauty Phi. He found that Amber Heard was the most beautiful face in the world.

According to his study, Amber's "eyes, eyebrows, nose, lips, chin, jaw and facial shape were measured and 12 key marker points were analyzed and found to be 91.85 percent of the Greek ratio of Phi, which is 1.618."

Rihanna and Scarlett Johansson also tallied high on that study.
