The supermodel got emotional while filming her appearance on UK TV's The Jonathan Ross Show - which will air Saturday night - when she talked about how anger management classes saved her life.
The 43-year-old star - who has previously been arrested for throwing mobile phones at her staff - said: "I made anger management serious.
"Anger is an emotion. There were things I had to deal with. You have to deal with it."
As she teared up, she added: "I'm crying, you made me cry!"
But host Jonathan replied: "Oh fuck off, no I didn't!"
Naomi also opened up about her previous drug use - which included being addicted to cocaine for five years - saying she realised she had to quit because it was ruining her life.
She added: "I don't want to go back. No matter what it is that you're addicted to - you can be addicted to work - all it is, is an escapism.
"It's escaping something, no matter what. For me, I came to my realisation at 29 that I didn't like myself the way I was, and that was it.
"Every day is a new day - I'm no perfect human being. I'm just living and I'm just breathing."
Naomi also rolled back the years on the chat show when Jonathan tasked her with walking in a pair of Vivienne Westwood Super Elevated mock crocodile skin shoes, which have nine-inch heels, the same design she wore when she famously fell over on a catwalk in 1993.
The brunette beauty obliged, but it was a case of history repeating itself as she once again fell over.
