David Duchovny 

First, it was announced that David Duchovny was going to rehab for his sex addiction.

Then, he wanted everyone to think his problem was solely a porn internet addiction (aka “sticky keyboard syndrome”) and that he had always been faithful to his wife, Tea Leoni. 

Now, news has surfaced that he actually did cheat on his wife.  (Duh!)

The NY Daily News reports:

But The National Enquirer reports that Duchovny went into rehab because Leoni “finally caught him [cheating].”
He said Tea gave him an ultimatum: “Get treatment or our marriage is over,” a source told the tab, which is riding high after getting former presidential candidate John Edwards to admit his infidelity.
“At first, Duchovny tried to lie his way out of trouble, but eventually was overwhelmed with guilt and confessed,” The Enquirer contends.
US Weekly concurs that Duchovny, 48, “has a history of indiscretions,” according to “multiple sources.” The mag claims he put the moves on an extra on his Showtime hit, “Californication.” “They ended up making out,” alleges a source. “She later heard this wasn’t the first time he’d taken special interest in an extra.”

Hmm…a history of indiscretions that muliple people can confirm. That would be hard for a marriage to come back from.
