As Woods was reportedly cheating on his wife, Jungers was engaged at the time to businessman and Woods fan Derek Schmidt.
"On the night Jamie met him for the first time, I had just bought the new Tiger Woods computer game. The following morning she told me she had met Tiger Woods and he gave her his number – and like an idiot I got really excited about it," Schmidt told the Mirror. "I knew Tiger had come on to her and asked for her number. I knew that he called her whenever he came to Las Vegas. But she insisted that nothing was going on."
Tabloids have reported the existence of two other unnamed women. One, a 26-year-old waitress from Orlando, has hired lawyer Michael O'Quinn and claims to have had a two-year affair with the golfer but has not yet come forward publicly. The other anonymous woman is allegedly a London-based British broadcaster, whom the London Sun has called a "cougar."
Those women join the three others whose names were made public last week – Jaimee Grubbs, 24, Kalika Moquin, 27, and Rachel Uchitel 33.
Of those women, only Grubbs has come forward to admit an affair. Moquin will neither confirm nor deny a relationship and Uchitel has denied an affair.
Grubbs gave US Weekly recorded voicemails and text messages she said were sent by Woods.
She told the magazine she met the golfer in 2007, two months before Nordegren delivered their first child.
US Weekly released a voicemail 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 voicemail 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 voicemail. 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 voicemails 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.
