Tiger Woods’ image lay in tatters today as reports emerged over a third extra-marital affair.

The billionaire superstar apologised for letting his family down in a statement that alluded to “personal sins” and the forced exposure of “intimate details” of his life.

Newspapers today reported that Woods has been two-timing his wife Elin Nordegren with Las Vegas nightclub beauty Kalika Moquin (27). Tabloids claim Woods met sexy brunette Kalika in 2007 when she was a bar hostess at the Mirage hotel in Las Vegas. Sources in the gambling mecca claimed the pair last met in October when Ms Moquin visited the golfer in his suite at the MGM hotel.

She refused to deny the relationship when approached by The Sun.

“It is difficult for me because I now work as the marketing director for a high profile hotel in Las Vegas. I am not interested in fame and am very worried anything I might say could affect my career,” she said.

Speculation has mounted over the golfer's personal life since he crashed his car into a fire hydrant and tree outside his home in Florida in the early hours of Friday morning, after tabloid allegations that he had an affair with hostess Rachel Uchitel.

But Ms Uchitel has previously denied having an affair with the world's No 1 golfer.

Her lawyer Gloria Allred told reporters she will “make a statement about Ms Uchitel's relationship with Tiger Woods” at a press conference in Los Angeles today. It is understood Ms Uchitel (34) will attend, but she is not expected to speak.

The development comes after Us Weekly reported that a Los Angeles cocktail waitress claims she had a 31-month affair with Woods.

The magazine released what it said was a voicemail — provided by waitress Jaimee Grubbs — that a man who identified himself as Tiger left on her phone three days before his accident.

Ms Grubbs told the magazine she met Woods at a Las Vegas nightclub the week after the 2007 Masters — two months before Woods’ wife Elin Nordegren gave birth to their first child.

In the voicemail released by the magazine, a man says to Grubbs: “Hey, it's, uh, it's Tiger. I need you to do me a huge favour.

“Um, can you please, uh, take your name off your phone. My wife went through my phone. And, uh, may be calling you.

“If you can, please take your name off that and, um, and what do you call it just have it as a number on the voicemail, just have it as your telephone number. That's it, OK. You gotta do this for me. Huge. Quickly. All right. Bye.”

US gossip websites suggested the reports of an affair may have led to a domestic dispute between Woods and Ms Nordegren (29) leading up to the crash.

Yesterday Woods, who was cited for careless driving and told he must pay a fine of 164 dollars (£98.57) in relation to the car crash, did not comment directly on the claims. But he said: “I have let my family down and I regret those transgressions with all my heart. I have not been true to my values and the behaviour my family deserves. I am not without faults and I am far short of perfect.”

He said he was “dealing with my behaviour and personal failings behind closed doors” and added: “I will strive to be a better person and the husband and father that my family deserves.

“For all of those who have supported me over the years, I offer my profound apology.”

He went on: “The stories in particular that physical violence played any role in the car accident were utterly false and malicious. Elin has always done more to support our family and shown more grace than anyone could possibly expect.”

Woods was left dazed, bloodied and in need of medical attention to cuts to his face after the crash at 2.25am (7.25am GMT) on Friday. His wife told police she used a golf club to smash the back windows of the SUV in a bid to get her injured husband out of the vehicle. But since the incident there has been growing speculation over the circumstances leading up to the accident.

Police tried for three days after the accident to speak to Woods, but were repeatedly thwarted.

On Tuesday, Florida Highway Patrol announced that it had concluded its investigation into the incident and found that the golfer alone was responsible. It cited him for careless driving, a violation for which he will be forced to pay a fine and have a four-point penalty on his driving licence on conviction.
