Reality-TV star Dean McDermott, husband of actress Tori Spelling, Thursday said he has entered rehab for unspecified treatment.
"I am truly sorry for the mistakes I have made and for the pain I've caused my family," McDermott, 47, told People magazine in a statement. "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."
E! News added Thursday that McDermott was seen exiting a Los Angeles rehabilitation facility on Jan. 18.
McDermott, who hosts the Food Network show "Chopped Canada," has been in the media spotlight since December, when a Canadian actress told Us Weekly the two had a tryst in a Toronto hotel room early that month while he was promoting his series.
Neither Spelling, 40, nor McDermott have commented on the cheating allegation, but Spelling in late December was photographed out to dinner with the couple's children -- Liam, 6, Stella, 5, Hattie, 2, and Finn, 1 -- minus her wedding ring.
Also Thursday, TMZ.com reported that McDermott has not paid a photographer, a food stylist and props person who worked with him on a cookbook, "The Gourmet Dad," upcoming from the publisher Harlequin. The website said part of McDermott's $250,000 advance was to be used to pay his collaborators and Canadian taxes.
McDermott and Spelling's reality shows include the 2007-13 Oxygen series "Tori & Dean: Home Sweet Hollywood" and HGTV's announced "Tori & Dean: Cabin Fever," which went into production in August.
