Brooke Shields stunned America when she swore during a live TV chat show on Friday night.
The actress was promoting TV show Lipstick Jungle on Late Night with Conan O'Brien when she lost her cool while recalling a row she had with a taxi driver.
Shields explained her cab driver couldn't understand where she wanted to go as she was rushing to get to a recent New York function, and when she tried to show him the address on her iPhone, the man kicked her out of his taxi.
She explained: "He shoved my hand back and said, 'You get outta my cab, you f**king crazy person.'"
A startled O'Brien said: "Woah... This isn't the story you should be telling."
Shields continued the story by revealing she refused to leave the cab and pretended to act crazy, so the driver would get her to her destination quickly.
She added: "I did not stop talking like a crazy person... He kept jamming to slap me up against the plastic (glass behind him) but because I'm strong and I'm a New Yorker, I grabbed on."
The actress paid the cab driver and gave him a tip, but when she refused to close the door as she got out, the commotion between the driver and herself prompted a nearby cop to get involved.
Shields went on: "I said, 'Do you really think that I'm the one with the problem...?' He (cop) closed the door and I walked away. I thought I was going to be arrested. It was so harrowing."
