If other reports haven't already dispelled rumors their marriage was on the rocks, Keith Urban's latest joke regarding how he and Nicole Kidman work together should do it.

While attending the Producer's Guild Awards with his wife over the weekend, the country singer was asked if he would ever consider collaborating with his wife on a project in the past, and he had a cheeky reply to the question.

"Us? We collab every night, of course!" He joked as his wife giggled and hid her face in his shoulder by his side.

However, Urban wasn't all jokes, also admitting that he has so much pride for his wife, who is being honored with several nominations for her work in the movie Lion, including an Oscar nomination.

"The fact that all of this brings attention to the film is extraordinary," he said.

The couple have been the subjects of endless swirling rumors that they would be getting divorced for months, after an initial report last fall which claimed they hadn't seen each other in nearly two months. Since then, the pair have tried putting the rumors to rest, often gushing about one another in interviews and at red carpet events, and also appearing to look as in love as ever when they've been at events together.

The two recently got ahead of a potential rekindling of rumors by admitting that they wouldn't physically be able to support one another when Kidman attended the BAFTAs in London and Urban attended the Grammys in Los Angeles, as they are both nominated for awards those nights, but need to be apart because the ceremonies are both scheduled for Feb. 12.
