(contactmusic.com) - The Black Eyed Peas star FERGIE is desperate to have children and is already planning to turn to pop star pal Gwen Stefani for baby advice.The singer wants to work on starting a family as soon as she weds actor fiance Josh Duhamel, but admits she knows nothing about babies - so she'll consult as many starry mums as possible for tips.Fergie - real name Stacy Ferguson - says, "I'd like to ask Gwen (Stefani), because she's really done a great job."But she insists there's no way she could perform while she's expecting - like Stefani and new mums such as Jennifer Lopez and Christina Aguilera did.She adds, "I don't want to be touring... I know I don't want that. Because I get way too physical onstage."I don't think I could hold myself back. And I would just be scared to hurt the baby. I'd take time off to read books about having babies, because I have no idea about that. I've never really changed a diaper."
