There are plenty of reality shows about finding love, but sometimes real-life romances formed on shows like Survivor and Big Brother last longer than any on The Bachelor or Bachelorette.

"We are the new Tinder at Big Brother," host Julie Chen joked to ET’s Kevin Frazier.

She and Survivor host Jeff Probst weighed in on why contestants on their shows sometimes end up being lucky in love -- even if they don’t win the game.

"I mean Survivor, the first marriage we had was during a live finale," Probst agreed. "Since then, I think we've had probably another half dozen couples who've married. Some of them have kids."

So why are contestants on survival or game shows having better luck?

"The Bachelor, that's not an environment to meet somebody," Probst explained. "It's a fun show to watch. Survivor, for instance, you're living in extreme conditions with somebody. You actually do begin to bond on a real human level. So it doesn't surprise me that you might find yourself connecting with somebody in that way."

Chen agreed, adding that on Big Brother, the conditions are less extreme, but the connection between castmates is very similar.

"You're in this house that is cut off from the outside world so you don't have, like, your mean big sister going 'he's a loser' or what have you," Chen said with a laugh. "You don't have television, you don't have distractions. All you have is conversation 24/7."

"Even if you don't make a love connection," the Big Brother host added, "you are bonded for life with all your former roommates. You're in this rare exclusive group on your own."
