There's a reason it's Jenny from the block, not Jenny fresh off the boat.

Former NYC Mayor Bill de Blasio was hopping mad when pop singer and actress Jennifer Lopez dared to define what makes a New Yorker.

'Everybody wants to claim our city.'

"Everybody wants to claim our city, but you have to be born in New York. You have to be born in one of the five boroughs to be a New Yorker," Lopez said.

Purity test

Lopez's offhand comments, which she made while appearing on "SubwayTakes with Kareem Rahma," prompted the Democrat former mayor, who led the city from 2014 to 2021, to call Lopez's definition "absolutely outrageous."

"There is no purity test," de Blasio claimed — asserting that New York is the "ultimate city of immigrants."

The 65-year-old continued his vehement defense of immigration by telling the New York Times the city's culture is actually the inverse of what Lopez was suggesting.

"In fact, it's been the opposite. We've said, 'Come here and become one of us.'"

New York state of mind

De Blasio attempted to explain that his self-identification as a New Yorker comes from "how long I've lived here and because I raised my family here," not the fact that he was born in Manhattan in 1961.

"This place gave me everything in life," the former mayor went on. "Your definition of home is the place that means the most to you. New York City has been my whole world."

It's a definition that Lopez would no doubt reject. In her appearance, she stressed that even if a person had lived in NYC for 50 years, he still wasn't cut from the same cloth as those who were born there.

"I have to say, no, you live in New York. You take on characteristics of New Yorkers. ... When you're born in New York is when you're really a New Yorker."

Emotional rescue

Lopez finished the short interview by advocating for schools to teach "self love" from elementary school through college, saying that if students couldn't pass tests based on being a good person, they shouldn't be allowed in society.

"Because they teach us things intellectually, but an intellectual motherf**ker with no emotional intelligence is dangerous! It's a dangerous person. Okay?" she remarked.
