Good Charlotte frontman Joel Madden has legions of fans eager to act as a sounding board for the band’s upcoming studio album, Cardiology.

At the end of the day, however, Madden says it is his 2-year-old daughter Harlow Winter Kate whose opinion he values most.

“She says yea or nay when I record a demo,” he explains in a new interview with the Los Angeles Times. “She gives me the honest reaction.”

Happily proclaiming himself “the best I’ve ever been,” Madden is acutely aware of just how much he has to be grateful for in fiancée Nicole Richie, Harlow and the couple’s 7-month-old son Sparrow James Midnight.

“I have two kids that are my life — they’re my entire world,” he says. “I have an awesome partner who is really supportive; She makes me the best version of myself that I’ve ever been.”

Of that commitment to his family of four, Madden explains, “I think you can decide to be the best dad and partner you can be, or you can run from it.”

Noting that “it’s a heavy thing when your life changes,” Madden, 31, says it has ultimately been a change he welcomes.

“My kids make me feel good about myself,” he insists. “I’m not really worried about succeeding or failing.”
