The celebrity cheater: Tiger Woods, high-profile professional golfer.
The other woman: Numerous.
What was gained: Zip. Zilch. Nada. There have been no winners and plenty of losers since Thanksgiving 2009, when Woods backed his SUV badly out of his Orlando, Fla., mansion and straight into tabloid hell. Tiger's public confession of numerous affairs and a stint in rehab did little to repair his marriage or contain the damage.
What it cost: Does "everything" sound about right? For starters, his divorce from wife Elin reportedly cost Woods $100 million, two Florida homes, an apartment and $2.2 million estate in Sweden, plus physical custody of daughter, Sam, and son, Charlie. There's also the $22 million in lost endorsement deals with Gatorade, AT&T and Accenture (though he retained Nike and Gillette).
Last but not least, there's his golf game. In 2009, the last PGA tour before the scandal, Woods won six tournaments, earned $10.5 million and placed first in the FedExCup standings. The following year, he finished in the top 10 twice, earned $1.3 million and fell to 112th in the FedExCup standings.
Then again, with a net worth estimated at $500 million, Tiger won't starve.
