HOT CELEBRITY

TIGER Woods, whose aversion to intimate revelations is legendary, is considering an invitation to appear on the sofa of talk show queen Oprah Winfrey.

For the interview to work - quite possibly with Elin Nordegren, the wife on whom he cheated, by his side - Woods, 33, would have to engage in the sort of public confessional that has been anathema to him.

His minders have not granted such access since a 1997 interview with men's magazine GQ backfired after he was quoted telling dirty and racial jokes.

That profile also hinted that when he was not playing the fairways, he was playing the field from what some in the sport call the real PGA - the ''Party Groupie Association'' (rather than the Professional Golfers Association).

The Oprah strategy is under discussion in Camp Tiger as a series of tawdry new claims emerge about Woods' alleged infidelities after he admitted unspecified ''transgressions'' and ''sins'' last week.

In the most recent, it emerged over the weekend that an unnamed waitress at a ''VIP cocktail bar'' in Orlando has hired a lawyer as she prepares to go public with claims of an alleged two-year affair that began in 2004 when she was 20, according to celebrity news website TMZ.

There were also reports of several other alleged affairs in the US and one some years ago in London, purported to have been with an unmarried television newsreader.

Over the previous few days, he had been linked in a string of reports to Rachel Uchitel, a New York party planner, Jaimee Grubbs, a Los Angeles cocktail waitress, and Kalika Moquin, a Las Vegas club marketing manager.

A financial deal was reportedly under way to secure the silence of Ms Uchitel, whose sexual encounters with Woods were allegedly fuelled by a prescription sleeping drug, Ambien (which is said to enhance sex in the minutes after it is taken), according to her friends quoted on website radaronline.

Meanwhile, Ms Grubbs said she had racy texts and voice messages to prove she had had a 31-month affair with Woods.

The latest claims come as lawyers for Woods and Ms Nordegren negotiate an upgrade of the ''prenuptial'' agreement signed before their Barbados wedding in 2004.

While it is usually divorce that hits the famous hard in their wallets, Woods will have to dig deep just to keep the mother of his two young children married to him.

Ms Nordegren will receive an immediate $US5 million ($A5.46 million), with staggered payments worth up to an additional $US55 million if she stays with her husband for another two years, a lawyer familiar with the negotiations told The Daily Beast website.
