The pair, who originally met on the set of "Family Ties" in 1985, say there are a few important things that make their marriage work: Separate DVRs and separate bathrooms are key. Also, Tracy says she and Michael have the same outlook when it comes to raising children. "We're very in sync with the parenting," she says.
And after so many years together, the couple rarely fight. "Literally, our memories are at the point where if we started to have the argument, we can't even remember what we're arguing about," Tracy says.
