Update: Despite sightings of McDermott outside of his Los Angeles home on Monday, February 24, a source tells ET that McDermott is still currently in rehab and visits his children regularly.
Tori Spelling's husband Dean McDermott has entered rehab, following reports of his rumored infidelity on his wife of seven years.
"I am truly sorry for the mistakes I have made and for the pain I've caused my family," McDermott tells People. "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."

In December, UsWeekly reported that McDermott, 47, cheated on Spelling with 28-year-old Emily Goodhand, while he was promoting his gig as host of Chopped Canada in Toronto. The couple has not commented on the report.
Spelling, 40, and McDermott have four children together: Liam, 6, Stella, 5, Hattie, 2, and Finn, 1.
"Their priority right now is their children," a source tells People.
But whether Spelling will stay with McDemott is reportedly up in the air.
