A racy royal cousin is coming to NYC -- and she'll be taking her clothes off!

Katrina Darling is a 21-year-old model and burlesque dancer who recently discovered that Kate Middleton (not to mention Pippa!) is her second cousin, once removed. Darling is set to perform her risque stage act, including a "God Save the Queen Routine" for the first time in the U.S., with a planned March 13 debut at the "Dropout" party at hotspot W.I.P. in Manhattan's SoHo neighborhood.

Darling and the Duchess of Cambridge, 30, have never met, and are connected through Katrina's grandmother, Jane Darling, who is the sister of Middleton's great-grandfather, Thomas Harrison. The performer still keeps a banking job at Barclays in London, and didn't discover her royal relation until Kate and Prince William got engaged in November 2010.

She told Page Six that she won't be shy when she performs next month.

"London sticks more to the traditional burlesque side of things, whereas New York really pushes the envelope."

Teases Darling of her act: "I take my clothes off, but I don't give away anything that should be kept for someone else."

The royal family hasn't objected to her routine, either, Darling said. And her coworkers at Barclays have been cheering her on as well. "They know that I do this on the side,…Everybody is really supportive. The English know how to laugh at themselves a bit more."

"This is her first time to the states," a source explains to Us. "They are flying her out. She doesn't care that she is Kate's cousin -- she was doing [burlesque] before Kate got engaged."
