Eleven years together aside, the "It" couple seemingly almost made a mess of their marriage on-air when they talked about cleaning the house.
"I'm very tidy, and she's not," Beckham, 35, tells DeGeneres in an interview airing Tuesday.
From her seat in the audience, the former Posh Spice, 36, fires back: "He always says that he is tidy, but you're not actually that tidy are you David?"
"We're going to have our first argument in 11 years," the soccer star says. But at least he's not playing the blame game: "I'm sure there are a lot of things that I do that drive her crazy," he adds.
The soccer stud, who sat on the sidelines at the World Cup this year due to an injury to his Achilles tendon, may have some apologizing to do – but at least he's on the track to physical recovery.
"I've never been out for so long before, so I kind of had to get myself around that because, like I said, I never had such a bad injury," he says. "There were moments when I thought maybe I won't play again, but I had so many positive people around – my friends, my family, my children, my wife."
