The holidays came amid a "great deal of tension" for Spelling and McDermott, after a source told PEOPLE last month, "They have gotten to a point where there are no easy fixes." The insider said that the couple would likely spend part of Christmas together "for the sake of the children."

"Tori still has major trust issues. Part of their relationship was never fully repaired after he was unfaithful," another source previously told PEOPLE. "They've been living separate lives. They will still have family meals and occasional outings, but it's for the kids."
