Uncle Sam is too late for Nina Agdal — Leonardo DiCaprio beat him to the punch.

Agdal, the 24-year-old Victoria’s Secret stunner who is reportedly dating DiCaprio, joined swimsuit model Hailey Clauson, this year’s Mermaid Queen, in turning Coney Island into a catfish-walk Saturday during the annual Mermaid Parade.

The annual celebration started at the corner of Surf Avenue and West 21st Street and ended at Steeplechase Plaza.
