Nicole Richie and Joel Madden have traveled the world, partied at exclusive clubs and signed autographs for adoring fans. So what impresses them these days? When daughter Harlow Winter Kate Madden, nearly 3 months old, gives them a grin. "The greatest thing about Harlow right now is that she laughs and smiles a lot," Joel tells Life & Style. "She wakes up every morning laughing and smiling - and it's the best part of my day." But there are tough new challenges ahead. In late March, Joel left for a Good Charlotte tour that will take him throughout Europe through mid-April. Nicole and Joel can't wait until he's back so they can resume their routine. "Nicole's world is about bottles, diapers and family dinners now," says the couple's friend. "Parenthood is the best thing that ever happened to her." Meanwhile, are wedding bells in Nicole and Joel's future? The two attended the wedding of Good Charlotte guitarist Billy Martin and longtime girlfriend Linzi Williamson on March 1. During his toast, Joel joked that "[They] beat us on the marriage, but we got you beat on the baby!" And, as Life & Style has reported, the duo have hired a wedding planner who's scouting locations in LA. "Nicole and Joel are totally in love," the couple's pal, American Idol host Ryan Seacrest, tells Life & Style. And they've got Nic's dad, singer Lionel Richie, behind them. "Lionel says that if Nicole were to take the next step, he would advocate that," says Ryan.
