Tiger Woods was last night facing claims he had a lengthy affair with a second woman.

A cocktail waitress has told a magazine she had 20 sexual encounters with the married golfer over 31 months.

The allegation came as Woods was charged over a mystery car crash linked to claims of an affair with the first woman, nightclub hostess Rachel Uchitel.

Woods, 33, is thought to have been knocked unconscious when he hit a water hydrant and a tree early last Friday.

And the father of two’s refusal to explain exactly what happened has fuelled speculation that he has something to hide.

A celebrity website alleges that his Swedish wife, Elin, 29, scratched his face and chased after his car with a golf club after a bust-up over Miss Uchitel.

The cocktail waitress, Jaimee Grubbs, claims she has an answerphone recording and text messages as evidence of her relationship with Woods.

‘He told me just last month quietly and secretly we will always be together,’ she told US Weekly.

‘He gave me the impression he and his wife had separate rooms.’

Miss Grubbs claimed they first had sex in a hotel room in San Diego but she did not give a date. ‘He just grabbed and kissed me and we started taking our clothes off and had sex,’ she alleged.

‘Afterwards, he was like “you should go”. He told me that he has a hard time sleeping in the same bed with somebody.

‘We never talked about golf. Sometimes we talked about his stressful life. He told me his life was overwhelming.’

The 24-year-old from Los Angeles claimed the affair began in April 2007.

She is said to have photos as well as more than 300 texts from him.

The magazine says it plans to publish online the answerphone message, in which Woods allegedly suggests his wife might suspect him of infidelity.

Woods also allegedly messaged the waitress last week – three days before his crash – to warn her that his wife had gone through his phone and ‘may call you’.

She claimed the golfer texted her in September to say: ‘I will wear you out soon. You just need some attention from me.’

In October, another alleged text said: ‘Change of plans. Meet me at the island hotel. It’s a little safer. Got us a room for the night. Room 905.’

Meanwhile, Florida Highway Patrol said it had completed its probe into Woods’s accident and would not be bringing any criminal charges.

Spokesman Kim Montes said there had been no claims of domestic abuse and insufficient evidence to seek a court order to look at the golfer’s medical records.

Woods will simply have to pay a £100 fine for careless driving with four points on his licence.

Miss Uchitel told the New York Post yesterday that she was no homewrecker.

‘I have not had an affair with Tiger Woods. It’s horrible to Tiger’s family,’ she added. ‘His wife must feel horrible. The worst part of it, it’s not true.’

She said she had welcomed Woods to a Manhattan club where she worked as director of VIP services and met him ‘for two seconds’.

Miss Uchitel, whose fiance died in the 9/11 attacks, said the source of the story was an acquaintance she had met just twice.

Woods, who has won 14 major tournaments, picked up £66million in prize money and endorsements last year.
