Singer, producer, father and now author?
Good Charlotte frontman and Nicole Richie beau Joel Madden has been mum about his literary aspirations in the past, but confirmed to PEOPLE Saturday that he is indeed working on a book.
"I'm lightly working on one," Madden, 30, said, before taking the field in
the Hollywood Stars Celebrity Softball game at Dodger Stadium, "but I don't want to put a book out there if it's not actually meaningful. I'm not going to go there unless I can deliver."
Though the project is in it's early stages, the soon-to-be father of two
already knows to follow the age-old advice given by all writing teachers – write what you know.
"It would be about my life," the singer says, "It would be about, mostly, the big changes in my life: Kids, relationships, moving to L.A…the big life changes that I've gone through."
Despite the potential rich Hollywood backdrop, don't expect your
typical celebrity tell-all. "If I put a book out, I want it to be something that matters to me," he says. "It has to be real
, you can't just put a book out, to put a book out."
He concludes: "I want every page to mean something."
