Fergie has a new name - she has officially changed her moniker to Fergie Duhamel.

The former Stacy Ann Ferguson has completely dropped her first names and opted to merge her stage name and her married name - and a judge gave the sign off on Friday (16Aug13), according to Tmz.com.

The singer, who has been married to actor Josh Duhamel for almost five years, requested the change last month (Jul13).
