Trouble in paradise for Hilary Duff and Joel Madden. They’re still in love and want to get married, but money is driving a wedge between them. The fact is, Hilary is making MUCH more money than Joel – an insider sniped “She earns more in a week than Joel has in his entire career.” Joel’s band Good Charlotte hasn’t done much in the last three years. Another issue is trust. Hilary is frequently on tour or on location and Joel has her bodygurads reporting her activities back to him. 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. She and her boyfriend have been known to snoop around each other phone books and emails. They’re trying to make it work – but it’s hard when you’re that young and ambitious and in love – ask Justin and Britney.
