The Duchess of Cambridge might want to reconsider sending a royal baby shower invite to her cousin.

Katrina Darling, who only found out she was related to Kate Middleton in 2011, is known for taking it all off in front of celebrities.

The 23-year-old recently performed a burlesque strip tease at the Life Ball on May 25 in Austria whose famous guests included former U.S. President Bill Clinton, Elton John, his husband David Furnish, model Karolina Kurkova and Kelly Osbourne.

The tattooed blond beauty began her performance dressed as a sexy queen in a red tulle frock, matching gloves and faux crown and carrying a gold scepter. But the royal garments didn't stay on for long!

Katrina disrobed for what we can assume was a rapt audience, and showed off red lacy undies which she quickly got rid of. Although the dancer wasn't completely nude, she may as well have been! Katrina stripped down to reveal her boobs (with nipple pasties) and a piece of fabric that covered her "crown jewels" down there.

While we don't know whether Middleton, who is expecting her first child in July, has made any contact with her long, lost relative, Darling isn't afraid to talk about her famous connection.

In fact, Katrina even defended the duchess when topless photos of Kate were published in European tabloid magazines in 2012. The burlesque dancer told Loaded magazine, "[Kate] was on private land and comfortable being in her own skin. I don't think she should be scrutinized for being comfortable in her own skin."
