Joel Madden and Nicole Richie have made it past the seven-year itch — they started dating eight years ago and got married in December 2010 — but the couple's relationship may not be up to scratch.
"Nicole and Joel are at odds over everything," an insider revealed, claiming Richie, 33, and Madden are "on the brink of divorce."
"They've been spending more time apart because all they do is fight when they're together," continued the source to In Touch. "Nicole can be very forceful when she doesn't get her way, and Joel doesn't respond well to that."
RadarOnline.com can reveal that the last time Richie was photographed out with her husband was over a month ago, on March 12, when the two joined Benji Madden and Cameron Diaz for dinner in L.A. to celebrate the Madden brothers' 36th birthday.
But just two days before, Richie was spotted house hunting — without her wedding ring — with no hubby in sight.
"If it wasn't for the kids, they'd be divorced already," explained the insider of the warring parents to daughter Harlow, 7, and 5-year-old son, Sparrow. "Nicole's trying to hang on for their sake, but she's at her breaking point."
