Kate Middleton's 21-year-old cousin Katrina Darling flaunted her royal lineage -- and everything else -- during her racy nearly-naked stage show in NYC last night.
Darling, who is the Duchess of Cambridge's second cousin once removed and has never met Kate, is a burlesque dancer and brought her erotic dance act to the U.S. this week.
It's safe to say Darling has been stripped ... of her title.
