Naomi accused of another PA assault

Naomi Campbell was accused yesterday of attacking another assistant - with a handheld computer.

The fiery supermodel, whose tantrums are well documented, is said to have beaten a female PA about the head with the fashionable Blackberry organiser and slapped her across the face.

Sources claimed the Streatham-born 34-year-old 'lost the plot' when the pair were working in Brazil last week and pounced on the aide.

One source claimed: 'Naomi was slapping her with one hand, and beating her with a BlackBerry with the other.' But Campbell's spokesman Rob Shuter insisted the model had not attacked personal assistant Amanda Brack.

An email attributed to Brack which he showed reporters says: 'Naomi has always treated me with great respect.'
