Tasha Robinson-White worked for Mayweather, 37, for 12 years operating within his inner circle as the boxer's 'right hand' woman - and has now written a tell-all book about her extraordinary career.

In an exclusive interview with Daily Mail Online she reveals how she witnessed 'Pretty Boy' Floyd's extraordinary rise from a cocky young sportsman to undefeated boxing champion of the world in five different weight classes.

In a sensational account of the sportsman's personal life Tasha, 42, reveals how Mayweather became deeply consumed by the trappings of wealth; lost $15 million after being duped by a conman; surrounded himself with an entourage of paid strippers and hangers on; and gave cash and presents to strangers.

She also exposes a vulnerable side to the arrogant champ who at his lowest point had talked about his own funeral after a domestic dispute with the mother of his children.

Tasha, whose book Right Hand To The Champ is published this week, was by Mayweather's side almost every day, fitting in around his unusual routine.

When the fighter was not in training he would sleep from 6am until 3pm each day before spending two hours dressing and grooming himself.

He selected what designer outfit to wear from his vast walk-in wardrobe, which included a separate room for his furs and a room for his leathers.

Then at 4.55pm he and Tasha would drive in separate cars to see his personal banker at a Bank of America branch near his Las Vegas home where he would withdraw, on average, a staggering $100,000 in cash.

'He didn't like credit cards,' explains Tasha. 'So he always wanted large amounts of cash with him at all times.

'He kept it in a large duffel bag which his staff called the 'pregnant duffel' because it was always bulging with money.'

Two burly security guards follow Mayweather wherever he goes to keep him and the cash safe.

Tasha said the boxer lived and breathed money and became more and more 'flashy and flamboyant'.

He even made his friends sit in the back of his car so he could ride with the duffel bag up front.

Tasha says he blew his money during extravagant shopping sprees, on expensive fine dining and lavish nights out.

He also liked to splash out on new cars, collecting luxury vehicles like 'toy cars'.

'I remember him buying six or seven cars in one day,' recalls Tasha.
