Despite working on opposite sides of the globe, "American Idol" judge Keith Urban and wife Nicole Kidman have no trouble keeping their marriage hot. What's this famous couple's method of choice?

"Sex texting," Urban revealed during an appearance on "The Ellen Degeneres Show" airing today.

These days, Urban, 45, is juggling his "Light the Fuse" tour with taping "American Idol" while Kidman, 46, is shooting a film in the UK. The couple have two daughters, Sunday Rose, 5, and Faith Margaret, 2, who are currently with their mom in London.

"I always structure my tours so that I'm never gone for weeks at a time. I'll do three shows in a row, be home for three or four days, go back and do three or four shows, and that works out good until 'Idol' comes along and fills in those days in between," Urban dished. "And that is doable until then a film comes along and that shoots in London. And, we're like, 'Okay, we'll figure this out.' So, we just make it work."

"We never text, we never email," he added. "Phone calls only, which I really love that."

Still, Urban admitted there are exceptions to the rules. Occasionally, the country music star comes up with more creative ways keep in touch his wife of seven years.

"Maybe one cool kind of, you know, a year. One of those kinds of texts, yes, one of those ones with the accompanying photo," he confessed. "One of those kinds of texts."

"What kind of text? What do you mean?" DeGeneres asked.

"Nice sex texting," Urban said bashfully. "I'm a little red right now."
