Dean McDermott cheated on Tori Spelling while shooting the show Chopped Canada in Toronto last year, and on Tuesday night’s episode of True Tori, he and Spelling debated his return to the Canadian hotbed to film the show’s second season.

The disturbing dilemma caused even greater strain between the two, who are documenting their crumbling marriage on the Lifetime reality show after McDermott strayed on the former Beverly Hills 90210 star with Emily Goodhand.

Viewers saw McDermott, 47, get the news that the show was renewed, which would entail him shooting in Rob Ford’s home base for two months.

Knowing his return would push 40-year-old Spelling’s buttons, McDermott phoned his friend Wolf and asked if he should take the job, as it would be like going “back to the scene of the crime.”

His pal told Dean he had to man up and do the show without getting into any more trouble. McDermott later told his wife he was offered the show again, and Spelling moaned to the cameras that she wondered how Dean could even think of going when “we’re working on our marriage.”

The actress was also concerned that McDermott would have to start work on May 8 or 9, exactly when she was scheduled to start filming Mystery Girls, the ABC Family show that would reunite her with Beverly Hills 90210 co-star
