Source: Tiger Woods in Sex Rehab

Tiger Woods is in rehab for sex addiction in Mississippi.

Two different sources have seen the world's #1 golfer in the Hattiesburg area. E! News has him at the entrance to the airport there around 10 p.m. Monday.

"He didn't look happy or sad, just straight," a witness says, noting that Tiger Woods got into the driver's seat of an SUV parked curbside and then drove off.

That sighting coincides with a Radar Online report that says the beleaguered star is currently in Hattiesburg to receive treatment at sex addiction facility.

Tiger was seen at Pine Grove Behavioral Health and Addiction Services. He checked in there this week to receive sex addiction treatment, sources claim.

If true, it would help repair his image, at least a little. Same with his Haiti relief pledge. Going completely off the radar hasn't helped quell Tiger gossip.

Tiger Woods is likely in rehab for sex addiction.

Two police cars pulled up to the clinic Friday afternoon and several officers went inside, showing no outward signs of a disturbance but of increased security.

The clinic is directed by Dr. Patrick Carnes, who pioneered treatment for sexually compulsive behavior, and is widely considered one of the best in the field.

Tiger Woods has not been seen in public since his infamous post-Thanksgiving car crash into a fire hydrant and tree exposed his dalliances with Rachel Uchitel.

That led to more than 10 women coming forward and admitting to sexual relationships with Tiger. His wife, Elin Woods, has not filed for divorce from him ... yet.

Whether she plans to is anyone's guess, although we reported in December that Tiger was planning a rehab stint after the holidays to help salvage his marriage.
