Tori Spelling and Dean McDermott

Tori Spelling's husband insists he isn't "a monster."

Dean McDermott, who has been battling to save his marriage to the former 'Beverly Hills 90210' actress since he had a two-day fling with a waitress late last year, says he only cheated on her because he was insecure.

The 'Chopped Canada' host, who sought treatment in rehab for sex addiction in December, told 'ET Canada': "The affair was more about how I was feeling about myself than having an affair.

"I messed up and I'm owning up to it and I'm getting help. But to label me a monster or evil is very hurtful."

He added: "You know, I'm not the first person to ever cheat on his wife."

But the 41-year-old actress, who is currently in hospital in Los Angeles, hinted she is might be preparing to split from Dean, with whom she has four children, Liam, seven, Stella, five, Hattie, three, and Finn, two.

The blonde beauty shared a photograph of herself in bed at Cedars-Sinai Medical Centre, with the caption: "This sick in hospital I finally see how quickly life can take it all away frm you. We all need 2 step up frm inside& go 4 it! W/our friends by our side. Sadly I've finally faced truth that 1 person will never be there 4 me #TrueTori (sic)"

Dean blames their upcoming reality TV series for her health problems.

He said: "The show we're shooting is obviously very emotional. It's six days a week. It finally caught up with her and took its toll, so she has bronchitis, sinusitis and pneumonia and she's getting great care at the hospital."
