The troubled twosome were spotted holding hands while doing some last minute Christmas shopping at Target with their baby, Beau, in tow.
Spelling, 45, and McDermott, 52, looked like they'd patched things up during their outing to the discount store.
The reality TV stars went through a bunch of marriage strife in 2018, as Radar has extensively reported.
An insider told Radar the pair have been at each other's throats for months, arguing over their money woes, parenting differences, and the actress' persistent health issues.
Just after the former Beverly Hills, 90210 star and her husband celebrated Thanksgiving at the Allegretto Vineyard Resort, the couple got into an explosive argument at home — and she kicked him out of their Los Angeles-area house, a source said.
But on Saturday, Dec. 22, Spelling and McDermott couldn't have looked more affectionate and happy together.
It's no surprise they would show up at the Target store, as they've battled financial issues for years.
As Radar has reported, Spelling and McDermott were hit with a $220,000 default judgment in a bitter legal battle against City National Bank over an unpaid $400,000 loan.
The pair reportedly also owed the IRS close to $1 million in taxes last year.

Spelling and McDermott were all smiles and handsy together at the Target store in Woodland Hills, Calif., three days before Christmas.
The two took their youngest child, baby son Beau, born in March 2017, on their shopping day. They have four other kids.
"Tori and Dean looked like they were still very much in love as the held hands on their way into Target and even stopping to kiss a few times in the store while shopping," an onlooker said. But in March 2018, cops were called to the couple's home twice in one week for well-being checks on Spelling.
The two mostly bought toys, electronics, clothes and beauty supplies while shopping at the store. They even bought a new cell phone.
It was a far cry from their Thanksgiving, when a source told Radar that Spelling and McDermott got into an argument at their L.A. home.
"Tori and Dean are having serious problems," a source told Radar. "It got so bad she kicked him out, and he slept at a hotel."
The heated exchange started over The Last Sharknado actress' lackluster career, the source explained. "She blames him for her not having a career. She said if it weren't for him and his desire for such a big family, she'd be working," the source said. "Dean exploded. He told her not to blame him!"
"This happens all the time," the source insisted. "If they have a fight, she will ask him to leave and he does." Spelling and McDermott usually kiss and make up, the insider revealed. As Radar reported, on Tuesday, Dec. 11, Spelling and McDermott turned up at WE Tv's Real Love: Relationship Reality TV's Past, Present and Future bash, despite their Thanksgiving battle. And they were just like any other couple shopping for toys for their kids on Dec. 22!
