Dean McDermott, the estranged husband of actress Tori Spelling, has checked into rehab in Los Angeles. The actor and reality television show star, who appeared alongside his wife and children in Tori & Dean: Home Sweet Hollywood, has not disclosed why he has headed for treatment but the decision seems to have been made in the midst of allegations that McDermott cheated on his wife of seven years.

The couple hit a rough patch in December 2013 when Us Weekly reported than McDermott had had a one night stand with 28 year-old Canadian Emily Goodhand in early December. The gossip magazine alleged that McDermott had claimed that “he and Tori had a sexless marriage” to Goodhand before they hooked up.

The couple are also said to be experiencing financial difficulties.

"I am truly sorry for the mistakes I have made and for the pain I've caused my family. I take full responsibility for my actions and have voluntarily checked myself into a treatment center to address some health and personal issues," McDermott said in a statement released by his representative Thursday, via CNN. "I am grateful to be getting the help I need so I can become the husband and father my family deserves."

Spelling and McDermott were both married to other partners in 2005 when they met filming Lifetime TV movie Mind Over Matter and immediately began an affair. They were married by May 2006 and by 2012 had four children together, two sons and two daughters.

Though no official statement has been released regarding the purpose of McDermott’s rehab stay, an insider speaking to Life & Style claims that the actor is trying to combat his sex addiction. “[Tori has] told Dean she'll leave him if he doesn't get help for sex addiction. She's finally laying down the law because she knows things can't continue like this,” they revealed.
