Tori Spelling and Dean McDermott have no plans to divorce following allegations of infidelity and reports of them living separate lives, according to an insider.

"Rumors about cheating have followed them their whole marriage, and it really takes a toll on her," a source told People in its latest issue. "[But] I don't think they feel divorce is an option."

Us Weekly published a cover story in December claiming McDermott, 47, cheated on Spelling, 40, with 28-year-old model Emily Goodhand earlier that month. McDermott was in Toronto to promote his new hosting gig on Food Network's Chopped: Canada, and reportedly invited Goodhand up to his hotel room after meeting her at a dinner with friends.

Since news broke Christmas Eve of the alleged affair, speculation about the state of their marriage has run rampant. Neither one of them have publicly addressed the claims.

Sources told E! News the couple recently purchased a home together, but that McDermott is nowhere to be seen on the property since the cheating scandal made headlines. The couple is reportedly living separately.

"Dean hasn't been seen at the house very much. Right now he hasn't been there in several days," a source said.

Spelling has taken to focusing most of her time on her children and making sure they are not hurt by the rumors. She's been seen in public with her four kids several times, but has yet to make a public appearance with her husband.

"She's trying to keep things together for her kids and is putting on a happy face," a source said. "She's acting as normal as she can and sticking to the same consistent routine. She definitely doesn't want her kids to be affected by what's going on."

The source added that Spelling is not letting her husband of the hook so easily: she confiscated his phone to monitor his texts and calls.

Spelling, who reportedly always feared McDermott would cheat on her, has appeared thinner since the infidelity claims went to press.

"She's lost like 10 pounds since the news broke, and everyone's worried about her," a source told Radar Online.

McDermott and Spelling met in 2005 on the set of the movie Mind Over Murder. They married in 2006 after leaving their individual spouses and have four kids together: Liam, 6, Stella, 5, Hattie, 2, and Finn, 16 months.
