Nicole Richie, Joel Madden marriage in trouble?

Nicole Richie and Joel Madden have been married for almost one year and in a relationship for five years. But according to a published report, they might not be together much longer.

Nicole is fed up with the "rock star lifestyle," The National Enquirer is reporting on its website, and is threatening to leave the Good Charlotte rocker if he doesn't spend more time with his family, which includes 3-year-old daughter Harlow and son Sparrow, 2.

"They've been having marital problems, mostly centered around Joel's intense work commitments related to his band," an "insider" tells The Enquirer. "Nicole has been complaining nonstop that Joel is like an absentee parent. When he's not sequestered in the studio with his bandmates, he's touring the globe. This isn't the life Nicole wants for her kids."

Is Good Charlotte even that big anymore? Why are they doing this much touring and promoting if they haven't been heard much on Top 40 radio since a string of hits eight or nine years ago? Maybe Joel is just a workaholic?

It's understandable that she doesn't want to be a single parent while he's touring and in the studio. And Nicole Richie and Joel Madden weren't together for very long before she got pregnant, so she might not have known what she was getting into at that time. The Enquirer reported last year that Nicole had an emotional breakdown over Joel's workload and fears that he was cheating, and the stress apparently hasn't gone away.

"She wants Joel to grow up and settle down," the insider tells the mag. "She still wor­ries that he'll stray. Nicole is constantly texting and calling Joel throughout the day to check in with him to make sure he's not up to no good (writer's note: that's never a good sign). When Joel announced a few weeks ago that he intended to go back into the studio to work on new material, she flipped. She tore into him and threatened to leave with the kids unless he recommitted himself to family life. She forced him into a corner and made him choose family over career. So he reluctantly announced to his bandmates that they needed a break."
