How many women has he cheated on Elin with at this point? Just ridic.

Apparently, Tiger Woods had an 18 month affair with 42-year-old mother of two Emma Rotherham... and then paid her half a million to keep quiet!

But a source tells News of the World that "Emma was his most recent mistress. They had a very, very passionate relationship and she has dozens of text messages and emails from him. If those came out they'd bury him. He absolutely adored Emma and loved the sex. So did she."

The source close to Tiger also claims that the sports star was "a sex addict" with Emma. "He never wore a condom," claims the insider. Plus, the source also says that Tiger enjoyed "drug-fueled sex sessions" with Emma.

And how did Woods pay her off? A member of his security team handed over a sports bag stuffed with 100 dollar bills. Classy.
