Fergie claims she never loses her temper because she has learned to control it in therapy.
The 'My Humps' singer, who is a former drug addict, is now so at peace that she hasn't had an argument for years.
Fergie, 32, said: "I've been in therapy for a few years so I don't really lose my temper.
"It sounds kind of corny but I like to discuss rather than yell.
"The last time was probably years ago in my early twenties when my ex-boyfriend threw all my clothes off the balcony. We didn't break-up, though. It was a very 'exciting' relationship. Fiery!"
Despite her calm outlook, the Black Eyed Peas singer believes misery is a better emotion for making music.
She said: "Tragedy is more interesting."
Fergie is now dating 'Transformers' actor Josh Duhamel. The couple live together in Los Angeles and Josh has installed a stripper pole in their home for Fergie to entertain him with erotic dances.
