Following his now infamous Thanksgiving car crash, and the subsequent revelations made about his private life, the shamed golf star has gone out of his way to stay clear of the spotlight, leading to mounting speculation as to his whereabouts.
But this week what is thought to be the first photograph of the dad-of-two, taken since the revelations, has been published.
A picture reportedly showing Tiger - wearing shorts, a T-shirt and a hooded top covering a baseball cap - walking in the grounds of a Mississippi rehabilitation centre has surfaced in the US.
The 34-year-old is said to have checked himself into the Pine Grove Behavioural Health and Addiction Services clinic in the remote town of Hattiesburg on December 30 – his birthday.
America's highest paid sports star is reportedly on a six-week Gentle Path programme for sex addiction, believed to cost around £37,000, according to a US news magazine.
Sources have said that he entered the clinic in an attempt to save his marriage to Elin Nordegren, 30, the mother of his two children; two-year-old daughter Sam and six-month-old son Charlie.
While others patients share rooms and undertake chores, Tiger is believed to have been granted his own chalet and has been excused from domestic jobs during his stay at the 24-bedroom facility.
And it is thought he is also receiving one-on-one treatment rather than group therapy.
The intensive six week course involves cognitive behavioural therapy, psychiatric consultations, shame reduction work and relapse prevention counselling.
Elin is expected to join in part on the therapy, joining his sessions during 'family week', which include a 'disclosure day'.
Officials at Pinewood would neither confirm nor deny Tiger's presence, although workers have been seen extending the facilities' exterior fence perhaps in an effort to increase security.
Earlier this week it was reported that Tiger - who apologised publicly to his wife for his "personal sins" - will be making a return to golf in the near future.
