The 40-year-old Beverly Hills 90210 alum was spotted at Disneyland in Anaheim, Calif. Saturday with her four children, Liam, 6, Stella, 5, Hattie, 2, and Finn, 16 months.
While the actress has failed to comment on the reports, an insider told Radar Online that she believes the rumors and has cried about it, but that her "obsession" with having a "perfect family" keeps her from taking action against McDermott or even commenting on the issue.
Spelling has kept a low profile since the rumors began, but she continues to be harassed by photographers as more gossip comes up.
On Monday, her rep told E! News that reports that the couple had been evicted from their home were completely false.
"Due to a clerical error a three-day notice was initially posted at the house," the rep said. "All payments have in fact been made, the lease is current and in good standing and the three-day notice has been effectively withdrawn."
The couple was last seen together Thursday as they stepped out in L.A.
