David Duchovny cheated on his wife for years before finally entering a rehab clinic for sex addiction according to a US magazine. The X Files star allegedly agreed to seek treatment after heartbroken Tea Leoni discovered his indiscretions and threatened to divorce him. 'He said Tea gave him an ultimatum: Get treatment or our marriage is over.'

Duchovny checked into The Meadows facility in Arizona last week and is currently completing a 35 day course. His wife has been to visit him at the centre several times. 'Tea drove to The Meadows every day during the four days she was in town,' the source is quoting as saying.
