American Pie actor Chris Klein has voluntarily checked himself into rehab following his second drunk driving arrest last week in Los Angeles. His blood alcohol level was three times the legal .08 limit. Klein, the former fiancé of Katie Holmes, checked into a 30-day rehabilitative program at the Cirque Lodge in Utah, which has previously treated Mary-Kate Olsen and Eva Mendes. His rep released the following statement to the press: "After recent events, Chris was forced to take a clear look at a problem he has been trying to deal with himself for years. He understands now that he can not beat this disease alone. He thanks everyone for their support as he takes all the necessary steps to deal with his addiction and asks for privacy while doing so."
