Los Angeles, California (CNN) -- A news conference called to discuss a woman's relationship with Tiger Woods was abruptly canceled by her lawyer Thursday.
Gloria Allred, the celebrity lawyer representing Rachel Uchitel, cited "unforeseen circumstances" when she announced the cancellation Thursday morning.
Rachel Uchitel denied having an affair with Woods after tabloids reported it last week, before allegations emerged linking him to another woman and before the golfer apologized for his "transgressions."
Uchitel, who works in New York, flew to Los Angeles Sunday to consult with Allred, a lawyer whose own Web site calls her the "most famous woman attorney practicing law in the nation."
Allred e-mailed journalists Wednesday saying she would "make a statement about Ms. Uchitel's relationship with Tiger Woods" at her Los Angeles law office Thursday.
Allred's initial announcement said Uchitel would attend, but not speak at the news conference.
Woods canceled plans to attend his own golf tournament in the Los Angeles area this week, citing injuries from an early morning car crash last week.
Woods posted a statement on his Web site on Wednesday that did not admit an affair, but he apologized for "transgressions" that let his family down.
The apology came on the same day US Weekly magazine alleged that Woods had an affair with another woman, Jaimee Grubbs, 24, whom it identified as a cocktail waitress.
The magazine also published what it says is a voicemail message from Woods to Grubbs.
"Hey, it's Tiger," a man says in the recording. "I need you to do me a huge favor. Can you please take your name off your phone? My wife went through my phone and may be calling you."
CNN could not independently confirm that the voice on the recording was Woods.
"I regret those transgressions with all of my heart," Woods said in the apology posted on his official Web site. "I have not been true to my values and the behavior my family deserves."
"I am not without faults and I am far short of perfect," the statement said. "I am dealing with my behavior and personal failings behind closed doors with my family. Those feelings should be shared by us alone."
Woods crashed his SUV outside his Florida home last week, sparking intense interest in the accident, which came a few days after The National Enquirer reported the golfer was having an affair with Uchitel, a New York nightclub hostess.
Woods paid a $164 fine for careless driving after investigators said he crashed the vehicle into a fire hydrant and tree.
