THE Black Eyed Peas star Fergie is trying to keep her engagement a secret by hiding her ring in her handbag when she's out in public. The LONDON BRIDGE singer accepted boyfriend Josh Duhamel's wedding proposal just before Christmas (06), according to US reports, but she doesn't want to make the happy news public until they have set a wedding date. America's Life + Style magazine claims Fergie, real name STACY FERGUSON, was showing off her four-carat diamond engagement ring at a pre-Christmas party at film producer Michael Bay's home on 15 December (06) - but has kept it hidden ever since. Duhamel's representative have denied the engagement news, but a friend of the couple tells Life + Style magazine, "They don't want to announce the engagement until they set a wedding date, but Fergie can't wait to marry Josh." Sources suggest the couple are considering a European wedding next summer (08). An insider says, "She wants a big, formal wedding."
