Channing Tatum, Wife Jenna Dewan's Marriage Secret Is To 'Be Honest'

What's Channing Tatum's secret to a happy marriage?

In an interview in Cosmopolitan's July issue, the actor revealed that he and his wife of almost four years, Jenna Dewan-Tatum, keep their marriage strong by being honest about how they feel about each other.

"You have to want [the marriage to work]. Jenna's and my thing is checking in with each other all the time, like 'On a scale from one to 10, how much do you love me right now?' And you gotta be honest, and you've got to want an honest answer," Tatum said. "I told a friend to do that. He asked the question and it turned into a huge fight, and I'm like, that's kind of the point."

Tatum and Dewan-Tatum met on the set of "Step Up" in 2005 and married in Malibu, Calif. in July 2009. Dewan is currently pregnant with their first child.

In 2012, Dewan-Tatum said one of their marriage secrets was to see each other at least every two weeks, despite their busy schedules.
