However, "it's not for them," added the insider. "It's for ratings and money."
McDermott had cheated on Spelling with a 28-year-old woman named Emily Goodhand while away on business. He had checked himself into a rehabilitation center in January, ultimately regretting his actions. Once Spelling discovered McDermott had been unfaithful, she was completely devastated yet appeared to want to work things out.
While True Tori has been airing the couple's sad story -- and it has seemed legitimate -- a source told Life & Style they're just good at acting.
"Tori and Dean think they have everyone fooled," said the source. "It is just completely fake. Together, Tori and Dean are a cash cow. That's why they'll stay together."
Spelling, 40, and McDermott, 47, have already renewed their vows once before. The event reportedly aired during their previous Tori & Dean reality series.
True Tori premiered in late April.
