Duff’s big bank roll is proving a difficult fact for Madden’s ego to face. A source told Charlton, "[Hilary] earns more in a week than Joel has in his entire career." Good Charlotte, the band that Joel fronts, has been out of the spotlight lately, which has made the rockers paychecks few and far between. The disparity between Joel and Hilary’s wealth has resulted in stress for the couple.

And allegedly Hilary has been relieving her stress by participating in a lot of girls’ nights out. According to Charlton, “When Hilary is out with the girls and gets someone's phone number, she writes it on her hand - so Joel can't find it in her phone.�? That’s because the pair reportedly spy on each other - checking their emails and address books for suspicious entries. And Madden uses his bodyguards as secret agents, looking after Hilary and reporting what she does back to Joel.
