LOS ANGELES -- Tiger Woods may be out of the rough in terms of his car crash, but his personal life is bound to take a hit after a voicemail, purportedly from the golfer to his mistress, goes public.

In an interview with Us Weekly magazine, 24-year old Southern California cocktail waitress Jaimee Grubbs claims she had a 31-month affair with Woods beginning when she was just 21-years old.

Grubbs said she saved a voicemail recording, photos and 300 racy text messages documenting their relationship.

US Weekly magazine on Wednesday posted exclusive audioof a voicemail Tiger allegedly left Grubbs just three days before he crashed his S.U.V. outside his Florida home saying:

"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. So if you can, please take your name off that. Just have it as a number on the voicemail. You got to do this for me. Huge. Quickly. Bye."

KTLA spoke with US Weekly's Melanie Bromley, the reporter who broke the story, and asked why Grubbs is coming forward now.

"She thought that she was really the only other special woman at the time in his life, aside from his wife and so she felt upset about that and that's why she wanted to speak out," Bromley said.

"She knows that what she did is not necessarily right but she wants to come clean and kind of be honest with people about her story," she added.

Grubbs says she began having an affair with Woods, 33, in April 2007.

According to the magazine, they went on to have 20 sexual encounters, meeting in hotels, checking into different rooms, and they would never be seen in public.

Grubbs says Woods left her racy text messages when he wanted to meet her, like, "I will wear you out."

Another time he texted "Send me something very naughty. Go to the bathroom and take (a picture)."

Grubbs says their last encounter was in mid-October, at the Island Hotel in Newport Beach.

Grubbs recently appeared on VH1's Tool Academy.

The show is described as "a competitive reality television show featuring "unsuspecting bad boys" who have been sent to "relationship boot camp".

The men, all of whom have been nominated by their respective girlfriends, initially think they are taking part in a competition for a title.

However, shortly after arriving they find out the truth: they are actually being entered into a "charm school" which focuses on teaching them how to behave as boyfriends.

Each week, one contestant is eliminated and his girlfriend must choose whether or not to stay with him."
