Naomi Campbell has undergone therapy to help her control her fiery temper, insisting she is now a calm person.

The supermodel insists her recent London arrest for assaulting a police officer during a luggage row onboard a flight was uncharacteristic - because she actually finds air travel peaceful and relaxing.

She says, "I travel a lot. I love travelling. It's peaceful in the air. Nobody can get me there.

"What has been written about me is out of the hemisphere. Just wrong. I don't care if they call me a bitch. A bitch is someone defending their rights. I'm a fighter.

"I've learned to meditate, to give myself some breaks during the day. I've rediscovered my good humour."

Campbell's claim comes on the back of a long history of temper tantrums.

Just last year she was sentenced to community service at New York's sanitation department after she was convicted of assaulting her maid with her Blackberry cell phone.
