'Dancing With The Stars' Season 25 Cast Revealed

When asked if the couples socialize, Maks Chmerkovskiy tells TooFab: "There's no dating, there's no lunching, there's no dinner."

It was a "Dancing With the Stars" first on Monday night's Season 25 premiere: Two married couples partnered up with each other's spouses in the hopes of coming home with the coveted Mirrorball Trophy.

But TooFab was surprised to discover that neither Nick and Vanessa Lachey nor Maksim Chmerkovskiy and Peta Murgatroyd dance with their competition/spouse when they get home from rehearsal.

"You gotta leave it on the dance floor," Nick told TooFab during our interview at the live taping of the premiere. "We're all doing different dances anyway, so it wouldn't really work for [Vanessa] and I to rehearse, plus it would last for about 10 seconds and then one of us would get mad. We're smart enough to know...go to rehearsal, work your tail off in rehearsal, and then leave it and come home and be mom and dad."

When asked if the foursome has gone on any double dates, Maks made sure to lay down the law.

"There's no dating, there's no lunching, there's no dinner," he told TooFab as he stood beside Vanessa. "There's just kids -- if you end up having time in the day -- and dance, and that's it."

But Peta said she was hopeful the couples would go out together "in the future."

"I think we should just go take a trip," Nick said to Peta. "Let's go train in Hawaii or something."

"Dancing With the Stars" airs Mondays on ABC.
