TIGER WOODS AND RACHEL UCHITEL ARE STILL HOOKING UP?...

According to In Touch magazine: Rachel Uchitel is still having an affair with Tiger Woods even though he has hit the double-digits mark, in terms of mistresses.

Apparently, Tiger "secretly flew out to LA on December 4 just so he could spend time with her." A source says that Woods and Uchitel "have been sleeping together the entire time since the scandal broke."

According to one of Tiger's pals, Tiger isn't on his main yacht, "he's staying on a decoy boat 500 feet from where Rachel has condo. He has been visiting her there."
