US Weekly released a voice mail recording provided by Grubbs that she said Woods left on her phone three days before his car accident. On the recording, a man Grubbs said is Woods asks her to remove her name from her outgoing voice mail message because his wife found his phone and might try to contact her.
"Hey, it's Tiger. I need you to do me a huge favor," Woods says in the message. "Can you please, uh, take your name off your phone? My wife went through my phone and may be calling you. If you can, please take your name off that and, um, what do you call it, just have it as a number on the voice mail. Just have it as your telephone number. You have to do this for me. Huge. Quickly. Bye."
Grubbs also claimed to have some 300 text messages from Woods.
The waitress told US that she had not seen Woods for more than a year until October, when they met in Newport Beach, Calif.
"He gave me a huge hug and said, 'I've missed you. You look amazing,'" Grubbs told US. "We cuddled, watched 'Angels and Demons,' then had sex. It was very romantic."
Grubbs' admission and the release of the voice mails prompted Woods to release a statement on Dec. 2, vaguely apologizing for "transgressions" and has not commented on any of the allegations since.
I have let my family down and I regret those transgressions with all of my heart," said Woods in the statement. "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," said Woods. "I am dealing with my behavior and personal failings behind closed doors with my family. Those feelings should be shared by us alone."
Moquin, alleged by Life & Style magazine to be carrying on an affair, with would not comment when reached by ABCNews.com.
The tabloid reported that Moquin, a Missoula, Mont., native met the golfer at the Bank, a nightclub at the Bellagio hotel where she works as a marketing executive.
"She's a marketing director at Bank. She throws parties, she hangs out with celebrities; that's her job," said co-worker, Bo Karlen.
The first of the cheating reports came just hours after Woods' car accident, when The National Enquirer named Uchitel, 34, a Las Vegas nightclub promoter.
Uchitel has denied rumors of an affair. She employed Gloria Allred, a California attorney famous for her high-profile clients.
"Not a word of it is true," Uchitel told the New York Post, about the allegations. "It's the most ridiculous story. It's like they are asking me to comment if there are aliens on Earth."
Uchitel began working nightclubs following her fiance's death on 9/11.
A call to Mark Nejame, a lawyer for Woods, wasn't returned.
