Bizarre world of Floyd Mayweather, by his right hand woman

   The cash-rich and often bizarre world of boxer Floyd 'Money' Mayweather Jr. is today exposed by his former executive assistant.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.

When he bought me my Mercedes the dealer told me that that was the 33rd Mercedes Benz Floyd had bought from them.'

'Money' Mayweather – who can earn $15,000 a second during some of his big pay-per view fights and is said to be worth $85million - once tossed $100,000 in cash around like it was confetti at a strip club. 'Then he'd fly us around on private jets. I've seen him drop $1-2million on pieces of jewelry, it got crazier and crazier,' said Tasha

In 2008 he hired out a recently closed strip club in Las Vegas to host a wild 'strip-off' contest to impress his close friend, hip hop artist T.I.He arranged for dozens of professional strippers to be flown in from around America to compete in the event as part of one of his infamous 'Mayweather weekends'.

  The girls were battling to win a $100,000 cash prize but as the night wore on an excited Mayweather decided everyone should come out a winner.

Tasha, who watched on in astonishment, recalls: 

'He went up on to the balcony and tossed wads of cash out on to the floor below, $10-$20,000 a time, there were strippers on their hands and knees picking $100 bills, it was crazy.'

Later Mayweather hosted an after-party at his Vegas mansion and during the wild night the boxer threw more cash into his swimming pool.He and his pals laughed as several strippers dived in to the retrieve the cash from the bottom.Tasha said Mayweather's favorite hobby was shopping, regularly visiting high-end department stores in Vegas, splurging on designer clothes and jewelry.

He would spend more than $35,000 on clothes and shoes at a time, sometimes every day.

But she says his generosity bordered on the ridiculous when he also insisted on buying all his staff clothes as well, including the bodyguards.

 She said:

'Floyd would buy $1,000 jackets, $300 jeans, dozens of shirts but then he'd buy stuff for everyone with him, which ever girls he was with, me, the body-guards.

'He'd even stop strangers in the store and buy them clothes or take care of their tab at the counter, it was crazy spending.'

Most of the time ladies' man Mayweather would insist on travelling with a minimum of a three girls by his side.The women, mostly strippers he had met at strip clubs, were paid to accompany him on his private jet or in one of his Bentleys.

And Tasha says she would see one girl or another leaving his house most days.When the boxer traveled back to his hometown of Grand Rapids, Michigan, he'd insist on paying for all of his entourage to fly first class.

When he arrived at his destination city he had a network of strippers on hand to meet him at the airport.But Mayweather was never interested in getting lap dances.

'One minute he'd call a stripper over at a strip club and she'd be butt naked, the next she's sat next to him fully clothed and they're hanging with us,' said Tasha.

'He'd tell them to tell their boss they're taking a leave of absence.'

Mayweather's generosity did get Tasha in trouble with her husband Kevin, however.

Her boss would buy her extravagant gifts, jewelry, designer clothes and once a white gold Cartier watch.

But the star crossed the line when he offered to have his personal jeweler clean Tasha's wedding ring.

She said: 

'When it was returned I discovered Floyd had paid for a $10,000 diamond to be installed in the ring.'As you can imagine my husband Kevin wasn't impressed at all.'

 Despite his generosity Mayweather's staff would often go months without being paid their salary

'He would say things like, 'well I bought them a Rolex didn't I,' explained Tasha.'Getting paid by Floyd was completely unpredictable, if the wind was blowing south, if he was in a good mood, then he may decide to pay you, or you'd just have to wait.'But he was so generous other times that you put up with it.'

 To frustrate his staff further, Mayweather often placed large bets of $40,000 plus on football or basketball games.Tasha says Mayweather was obsessed with his closet and would instruct staff to clear it out every 60 days, throwing away clothes that he deemed 'not in fashion' any more.

She says most things he only ever wore once before they were discarded. Tasha said: 

'It was a tough time for Floyd. The biggest blow was being scammed out of $15million.'Floyd met with a group of middle-men who introduced him to a guy called Three Comma Joe.

'He was impressed by Joe, he came in with the flossy blonde girl, he wore a nice big icy watch, he had the flash and Floyd was like, 'that's my kind of guy'.'After the deal was done they shook hands and began to hang out a lot, they were inseparable.'Floyd wired $15million to a Canadian bank accountand he was told to see a return very soon.

'But eventually Joe left Vegas and stopped returning phone calls, and the money train came to an abrupt halt. Nobody could find Joe, and no one could find Floyd's money.

'Not the $15 million Floyd originally invested, and definitely not the $5 billion he was promised to make in return. Life in the Mayweather camp got really nasty for everybody.'

 Tasha tells how furious Mayweather hired a team of private investigators to look for Three Comma Joe. 

Tasha had ended her working relationship with Mayweather in April, 2009 after she began to feel certain people within his entourage were blaming her for the $15million fraud, but the two remained friends.
