Tori Spelling's husband, Dean McDermott, has entered rehab, his publicist, Jill Fritzo, confirmed Thursday.

The 47-year-old actor, who has been the subject of recent infidelity rumors, said he's being treated for "some health and personal issues."

He said in a statement to People magazine that he's "truly sorry for the mistakes I have made and for the pain I've caused my family."

He added, "I take full responsibility for my actions and have voluntarily checked myself into a treatment center to address some health and personal issues. I am grateful to be getting the help I need so I can become the husband and father my family deserves."
